Comcast & Xfinity Customer Service & Arbitration

How to Contact Comcast / Xfinity (And What to Do When They Won’t Help)

Trying to reach a human at Comcast about a bill that grew overnight, a charge for equipment you returned, an internet speed that doesn’t match what you pay for, or a contract you can’t escape? Phone numbers and addresses are below. If you’ve already called and been told the same script three times, there’s a second option most customers don’t know about: arbitration.

A note on names. Comcast is the corporate parent; Xfinity is the consumer brand. Internet, TV, voice, home security, and Xfinity Mobile all bill under Xfinity but are operated by Comcast Cable Communications, LLC. The arbitration agreement and escalation path are the same regardless.

Comcast / Xfinity customer service contacts

Start with the front door. Most billing problems get solved at this layer if you reach the right person.

General customer service

1-800-XFINITY (1-800-934-6489) — Xfinity internet, TV, voice, home services
1-800-COMCAST (1-800-266-2278) — alternate corporate line, same call center
Live chat and online support: xfinity.com/support/contact-us

Xfinity Mobile: 1-888-936-4968 · Terms: xfinity.com/mobile/policies/customer-agreement

Comcast Business: 1-800-391-3000

Fraud and account security. If you suspect unauthorized account access or charges, ask the agent to escalate to the fraud team and request a written case number on the spot.

Executive escalation. When ordinary customer service has not produced a response, Comcast maintains an Executive Customer Relations team (sometimes called the Office of the President). It is not advertised on the main support page. The corporate switchboard can route you there.

Comcast corporate switchboard: (215) 286-1700
Corporate headquarters: Comcast Center, 1701 John F. Kennedy Boulevard, Philadelphia, PA 19103-2838

A short, factual letter to a named officer — naming the dispute, dollar amount, dates you called, and the resolution you want — sometimes succeeds where the call center failed.

If escalation also fails, the next layer is regulatory: the Federal Communications Commission consumer complaint portal, your state Attorney General, your state public utilities commission, and the Better Business Bureau. None of those force Comcast to refund or release you, but they create a paper trail.

Mailing addresses

For written disputes, arbitration correspondence, or formal opt-out notices, Comcast routes through its legal department in Philadelphia. The address below comes from Comcast’s published Visitor Agreement and Xfinity Agreement for Residential Services.

Comcast — Legal Department / Arbitration
1701 John F. Kennedy Boulevard
Philadelphia, PA 19103-2838
Arbitration opt-out website: xfinity.com/webarboptout

Send dispute letters certified mail with return receipt for proof of delivery.

What if Comcast says no?

You’ve been polite. You’ve been firm. You’ve been transferred four times. The bill is still wrong, the modem you returned is still on the account, or the contract you tried to cancel is still active.

Here’s what most customers don’t realize: when you signed up for Xfinity, you agreed to arbitration. That clause cuts both ways. Comcast can’t drag you into court, but you can’t drag Comcast into court either. The forum is arbitration, administered by the American Arbitration Association.

That sounds intimidating. It isn’t. Arbitration is a paperwork-driven process run by a neutral arbitrator, often resolved without anyone stepping into a room. Consumer fees are capped. You don’t have to be a lawyer. A bill wrong by a few hundred dollars is a fileable claim.

What Comcast’s arbitration clause says

The Xfinity Visitor Agreement and Xfinity Agreement for Residential Services both contain a mandatory binding-arbitration provision:

“Any Dispute… involving you and Comcast shall be resolved through individual arbitration… Arbitrations shall be administered by the AAA pursuant to the most recent version of its Consumer Arbitration Rules.”

Plain English. Four things in that clause:

Disputes go to arbitration, not court — except small claims court, still allowed if the claim fits your state’s dollar limit (typically $5,000 to $15,000) and is not aggregated with anyone else’s.
The forum is fixed: American Arbitration Association under its Consumer Arbitration Rules.
You give up class actions and jury trial.
For claims under $75,000, Comcast pays the AAA and arbitrator’s fees; your only out-of-pocket is the capped consumer filing fee.

The clause also includes a 30-day opt-out window for new customers (FAQ below). Source: Xfinity Visitor Agreement — Section 13.

How Comcast arbitration actually works

A consumer arbitration case against Comcast moves through a predictable sequence. Most cases run three to nine months from filing to resolution.

Demand for Arbitration filed with the AAA at adr.org, naming Comcast Cable Communications, LLC and stating what you want — refund, equipment-charge reversal, contract release, credit restoration.
Filing fee capped under AAA’s Consumer Arbitration Rules and Fee Schedule at $200 for most claims. Comcast pays the balance and the arbitrator’s fee when the claim is under $75,000, per its own arbitration clause.
Comcast’s answer from outside counsel, typically within 30 to 45 days. That response often opens settlement talks before the case is fully briefed.
Exchange of information — bills, account notes, equipment-return receipts, technician logs, speed-test records. Much lighter than court discovery.
Hearing (if needed) at a location convenient to you, or by phone or video. Smaller cases are decided on the written record alone.
Award. The arbitrator issues a written, reasoned decision. If it’s in your favor, Comcast is required to pay.

Settlement is common at stages 3 and 4. Carriers often prefer to resolve a $400 billing dispute with a check than pay a lawyer to brief it.

What U. S. Arbitration Corp. does in Comcast cases

U. S. Arbitration Corp. is a consumer-arbitration advocacy firm that has handled more than 60,000 cases. For Comcast and Xfinity matters, the firm:

Drafts and files the AAA Demand for Arbitration on your behalf
Advances the consumer filing fee and handles AAA correspondence
Communicates directly with Comcast’s outside counsel so you don’t have to
Negotiates settlement when that’s the right move; arbitrates to award when it isn’t
Works on contingency — 9 percent to 21 percent of what the firm recovers. No recovery, no fee.

Not every dispute is a strong arbitration case, and we’ll say so during the case review.

Common Comcast / Xfinity disputes

Most of the Comcast and Xfinity cases that come in fall into a handful of patterns:

Surprise fees and unrecognized charges — broadcast TV fees, regional sports fees, equipment rental on a box you own, taxes and surcharges that exceeded the activation quote.
Contract renewal and early-termination disputes — auto-renewal into a new two-year term without consent, early-termination fees after a service-quality cancellation, promised retention credits that never appeared.
Equipment-return charges — being billed for a modem, cable box, or remote you returned to an Xfinity store and have a receipt for; charges months after return; collections for equipment you never received.
Service-quality failures — chronic outages in areas Comcast’s coverage map said were covered, technician no-shows, repeated truck rolls that didn’t fix the problem, billing during documented outages.
Internet speed disputes — paying for 1 Gbps and consistently measuring a fraction on Ethernet, throttling complaints, data-cap overage charges that didn’t match policy.
Billing errors and double-billing — duplicate charges, billing after a documented disconnect, accounts opened in your name without authorization.
Wrongful collections — disputed balances turned over to a collection agency, sometimes years after the account was closed.

If your situation doesn’t fit those buckets, ask anyway. The case review is free either way.

For context: the 2016 FCC Comcast Consent Decree resolved an investigation into “whether Comcast wrongfully charged customers for unauthorized services and equipment,” and a 2025 FCC $1.5 million consent decree addressed a vendor breach of subscriber data. Past enforcement doesn’t guarantee any individual outcome, but it confirms the pattern is documented.

Frequently asked questions

How do I opt out of Comcast arbitration?

The opt-out is available only within 30 days of first access to or use of Comcast service. Within that window, opt out (i) online at xfinity.com/webarboptout, or (ii) by mail to Comcast, 1701 John F. Kennedy Blvd., Philadelphia, PA 19103-2838, ATTN: Legal Department / Arbitration. Your notice must include your name, address, account number (or telephone number if not a subscriber), and a clear statement that you do not wish to arbitrate. Opt-outs sent after the window are not effective. (Source: Xfinity Visitor Agreement — Right to Opt Out.)

Is Comcast the same as Xfinity? Which name goes on the demand?

Same company. Xfinity is the consumer brand; the legal entity is Comcast Cable Communications, LLC. The AAA Demand is typically captioned Comcast Cable Communications, LLC d/b/a Xfinity. Xfinity Mobile customers fall under the separate Xfinity Mobile Customer Agreement, which has its own arbitration provision.

How long does Comcast arbitration take?

Most cases resolve in three to nine months from the date the Demand is filed. Early settlements close in weeks; contested cases that reach a full hearing take longer, but AAA’s Consumer Arbitration Rules cap the timeline tighter than court would.

How much does it cost?

Under AAA’s Consumer Arbitration Rules, the consumer’s filing fee is capped at $200. For claims under $75,000, Comcast pays the balance of AAA’s fees and the arbitrator’s fee under its own arbitration provision. If U. S. Arbitration Corp. files for you, the firm advances that fee — nothing out of pocket to start.

Can I sue Comcast in small claims court instead?

Yes. Comcast’s arbitration clause preserves small claims, as long as the claim is not aggregated with anyone else’s and is within your state’s dollar limit ($5,000 to $15,000). For larger disputes or cases that need documentary discovery, arbitration is usually the better forum.

What if I returned my equipment and Comcast still charged me?

Equipment-return disputes are one of the most common Comcast arbitration patterns. Bring your Xfinity store receipt or UPS tracking number. Even years-old receipts have resolved cases. If the charge has gone to collections, that doesn’t extinguish the dispute — it just adds a defendant.

What happens after I submit the form?

Intake will call you within one business day — a ten-to-twenty-minute call to collect facts, dates, dollar amounts, and documents. An attorney reviews the file before the firm decides whether to take it. If accepted, you receive an engagement letter spelling out the contingency rate and scope.
