Call Comcast to request cancellation

The only way to cancel Comcast service is to call them directly. You cannot cancel online, through the Comcast app, or by email. Call 1-800-934-6489 and tell the representative you want to cancel your account. Have your account number ready — you can find it on your bill or in the Comcast app.

The representative will ask why you are leaving and may offer you a discount or service change to keep you as a customer. You can accept or decline. If you decline, they will schedule your cancellation date. Ask them to confirm the date in writing — either by email or by mailing you a confirmation letter. Write down the representative's name and the time of the call.

Comcast will ask you to return any equipment you rented from them — typically a modem, router, or cable box. They will tell you where to return it during the call. If you own your own modem or router, you do not need to return it.

Key Takeaways

  • Call 1-800-934-6489 to cancel; this is the only method Comcast accepts.
  • Have your account number ready and ask the representative to send written confirmation of your cancellation date.
  • Return any equipment Comcast rented to you at the location they specify during the call.
  • Your final bill will arrive after your service ends and will include any prorated charges for the partial month.
  • Keep your confirmation number and the representative's name in case Comcast continues to bill you after cancellation.

Return equipment before your cancellation date

Comcast charges you for equipment that is not returned. The fee varies depending on what you rented — typically $15 to $25 per item. Return your equipment before your cancellation date, not after. If you return it after your service ends, Comcast may not process the return in time and will bill you for it.

You can return equipment at a Comcast service center, by mail, or sometimes at a retail location like Walmart or Best Buy. The representative will tell you which options are available in your area. If you return by mail, use the prepaid shipping label Comcast provides — do not pay for shipping yourself. Keep the tracking number until you receive confirmation that Comcast received the equipment.

Understand what happens to your final bill

Your final bill will arrive 1 to 2 weeks after your service ends. It will include charges for the days you used service in the final month, prorated to the day you cancelled. For example, if you cancel on the 15th of the month and your bill is normally $100, you will owe roughly $50 for that month.

Your final bill may also include charges for equipment not returned, early termination fees if you are cancelling before a contract ends, or credits if you overpaid. Check your bill carefully. If you see charges you do not recognize, call Comcast to dispute them before you pay.

Watch for continued billing after cancellation

Some customers report that Comcast continues to bill them after cancellation. This usually happens because the cancellation did not process correctly or because the representative did not cancel the right account. If you see a charge from Comcast after your cancellation date, call them when ready with your confirmation number and the representative's name from your original cancellation call.

Ask them to confirm that your account is cancelled and to reverse any charges after your cancellation date. If they refuse or cannot find your cancellation record, ask to speak to a supervisor. Keep records of every call — the date, time, representative's name, and what was discussed.

Cancel before moving or switching providers

If you are moving to an area where Comcast does not serve, you may be able to cancel without an early termination fee. Call and explain that you are relocating outside Comcast's service area. Ask them to waive the fee. They may ask for proof, such as a lease or utility bill showing your new address.

If you are switching to a different internet provider in the same area, you will likely owe an early termination fee if you are still under contract. The fee is usually $10 per month remaining on your contract, up to a maximum of around $120 to $180. Ask the representative what your fee will be before you confirm the cancellation.

Know what to do if you cannot reach Comcast by phone

If you have difficulty reaching Comcast by phone, you can try contacting them through their website at comcast.com or through the Comcast app. Select "Contact Us" and choose the chat or callback option. Explain that you want to cancel your service. They may transfer you to a representative who can process the cancellation, or they may provide you with a different phone number to call.

You can also file a complaint with your state's public utilities commission if Comcast refuses to cancel your service or continues to bill you after cancellation. The commission can investigate and force Comcast to correct the problem. Search "[your state] public utilities commission" to find the contact information for your state.

Frequently Asked Questions

Will I owe an early termination fee?

Only if you are cancelling before your contract ends. The fee is usually $10 per month remaining on your contract, up to around $120 to $180 total. Ask the representative during your cancellation call what your fee will be. If you are moving outside Comcast's service area, you may be able to get the fee waived.

What if I rented a modem from Comcast but I want to keep using it?

You cannot keep a rented modem. You must return it. If you want to continue using the same modem after cancelling, you will need to buy your own. Comcast modems are not compatible with most other internet providers anyway, so you will likely need a different modem for your new provider.

How long does it take for Comcast to stop billing me?

Your service will stop on the cancellation date you agreed to. Your final bill will arrive 1 to 2 weeks after that date. If you see charges from Comcast after your cancellation date, contact them when ready with your confirmation number.

Can I cancel just internet and keep cable TV?

Yes. When you call to cancel, tell the representative which services you want to cancel and which you want to keep. They will adjust your account accordingly. Your bill will change to reflect only the services you are keeping.

What if Comcast says I cannot cancel because I owe money?

Comcast cannot prevent you from cancelling because of an unpaid balance, but they will continue to pursue collection of that debt after your service ends. If you owe money, ask the representative whether you can pay it as part of your final bill or set up a payment plan before you cancel.
