COMCAST CANCELLATION

Note to those who have individual Comcast contracts (i.e.: you receive individual billings for optional services not covered by the bulk agreement): If you cancel your Comcast personal subscription, in addition to returning Comcast equipment, be sure to also cancel your personal service contract . An Xfinity store can cancel your add-on service contract; a UPS store cannot. Don't forget to get a receipt or reference number covering the entire transaction. 

Dropping AT&T for AB?: same cautionary advice: Cancel the service as well as returning the equipment.
