Call Comcast directly to start the cancellation process
Comcast does not allow you to cancel Xfinity online or through the mobile app. You must call their customer service line at 1-800-934-6489 to request cancellation. Have your account number ready — you can find it on your bill or in the Xfinity app. The representative will confirm your identity, review your account, and explain any fees you owe before processing the cancellation.
Call during business hours (typically 8 a.m. to 8 p.m. local time, seven days a week) to reach a representative faster. If you call outside these hours, you may reach an automated system that can schedule a callback or direct you to online chat support, though chat cannot complete a cancellation — it can only provide information or schedule a call.
Be prepared for the call to take 20 to 40 minutes. Comcast representatives are trained to ask retention questions and may offer discounts or service changes before accepting your cancellation request. You can decline these offers and proceed with cancellation.

Understand early termination fees before you call
If you signed a service agreement with Comcast, you may owe an early termination fee to cancel before the contract ends. The fee amount depends on how much time remains on your agreement and which services you have. Internet-only contracts typically carry lower fees than bundled packages (internet, TV, and phone combined).
Ask the representative for the exact termination fee before you authorize cancellation. They will calculate it based on your contract end date. Some customers have negotiated reduced fees or had them waived, particularly if they have been long-term customers or if Comcast failed to deliver promised service speeds, but this is not may provide.
If you do not have a contract — meaning you are month-to-month — you will not owe an early termination fee, only any outstanding balance on your account.
Return equipment within the 30-day window
Comcast will ask you to return all equipment during the call. This includes the modem, wireless router, cable box (if you have TV service), remote controls, and any other hardware Comcast provided. You have 30 days from your cancellation date to return everything.
You can return equipment by mail or at a local Comcast service center. If you return by mail, Comcast will provide a prepaid shipping label during the call or via email. Pack the equipment securely and keep the tracking number. If you return in person, bring all items to the nearest Xfinity Store or service location and ask for a receipt showing what you returned and the date.
If you do not return equipment within 30 days, Comcast will charge you a non-return fee for each item, typically $100 to $200 per piece. These charges will appear on your final bill. Keeping documentation of your return (tracking number, receipt, or photos) protects you if Comcast later claims you did not return something.
What happens to your final bill
Comcast will send you a final bill within one to two billing cycles after your cancellation date. This bill will include any prorated charges for the partial month you used service, any early termination fee, and any equipment non-return fees if applicable. It will also credit you for any prepaid balance or deposits you had on your account.
If your final bill shows charges you believe are incorrect — for example, a non-return fee for equipment you returned — contact Comcast billing at 1-800-934-6489 within 30 days of receiving the bill. Have your return documentation ready. Comcast can take 30 to 60 days to investigate billing disputes.
If you owe money on your final bill, Comcast may send the account to a collection agency if you do not pay within 60 days. This can affect your credit report.
Cancellation timeline and service cutoff
Your Xfinity service will stop on the date the representative confirms during your cancellation call. This is usually 7 to 10 business days after you call, though it can be sooner if you request it. After that date, your internet, TV, and phone service (if applicable) will no longer work.
If you need service to continue past your cancellation date — for example, if you are waiting for a new provider to activate — tell the representative during the call. Some customers have had their cancellation date moved back by a week or two, though this is not may provide.
Request written confirmation of your cancellation date via email or mail. This protects you if there is a dispute later about when your service actually ended or what fees you owe.
Alternatives if you want to reduce costs instead of canceling
If your reason for canceling is cost, ask the representative about promotional rates or service reductions before you hang up. Comcast often offers discounted rates for the first 12 months to customers who are considering leaving. You can also ask to remove TV or phone service and keep only internet, which may lower your bill significantly.
Some customers have had better luck negotiating by calling the retention department specifically. When you call 1-800-934-6489, you can ask to speak with the "customer retention team" rather than standard customer service. These representatives have more authority to offer discounts or waive fees.
What to do if you have a dispute after cancellation
If Comcast continues to bill you after your cancellation date, contact them immediately at 1-800-934-6489 and reference your cancellation confirmation number. Ask them to reverse any charges posted after your service end date.
If Comcast does not resolve the issue within 30 days, you can file a complaint with the Federal Communications Commission (FCC) at fcc.gov/consumers. The FCC investigates complaints about cable and internet providers and can compel Comcast to respond. You can also file a complaint with your state's attorney general office, which handles consumer protection issues.
Keep all documentation: your cancellation confirmation number, the date you called, the representative's name (if provided), your final bill, and any return receipts or tracking numbers. This evidence is essential if you need to dispute charges later.
