To close your account:
Drop off your equipment at any Comcast Service Center or XFINITY Store. Close your account and retain the receipt. Find a Comcast Service Center or XFINITY Store Location near you.
Comcast has teamed up with The UPS Store locations across the country to accept Comcast equipment returns. Simply bring your equipment with you to any The UPS Store location, and an associate will pack and ship your equipment back to Comcast. Visit www.theupsstore.com to find The UPS Store locations near you. The UPS store will give you a receipt with a tracking number so that you can track the progress of your return on UPS.com. Please allow up to two weeks for the return to be processed on your account. Call Comcast 1-800-COMCAST (1-800-266-2278) or 1-800-XFINITY (1-800-934-6489) and close your account.
How can I close my account?
You need to post your question rather than quote someone else's. If you're just wanting to discontinue services, take your equipment to your closet Comcast store and close your account there. Make sure you get a receipt for your equipment. Or, you can take your equipment to a UPS store and have them send the equipment back. Again, make sure you get a receipt. Note that if you're in a contract you will have an early termination fee.
If you're just wanting to suspend service service for a period of time the minimum number of days for a suspension is 90 days with the maximum of 270 days.
