After you return the equipment, it will be taken off of your account immediately, and your next bill will reflect the return (if applicable).
The UPS Store Locations
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.
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. After this time period, your next bill will reflect the return (if applicable).
