I've asked a Comcast employee to help you. You should expect a reply in this thread.
@jmccutch - You can set up services at a different location with the non-agreement package, so you can set it up and cancel at any time. On your current account, you can set up a seasonal hold. The duration of a seasonal suspend must be set for a minimum of 90 calendar days and no more than 180 calendar days. If you would like to get more details - please send me a private message. We already have an open conversation.
@IPghost - Are you referring to Prepaid services? We have a Prepaid internet service and Prepaid Instant TV. You can find more information here: https://www.xfinityprepaid.com/. But it's a prepaid service not a post-paid one. You can also sign up for a non-agreement promotion so you won't have a contract and you cancel your services at any time. For the Prepaid services you will have to cancel your current account. With the non-agreement promotion - I can check what we have available in your area if you send me your full name, the account holder's name and address as it listed on the billing statement, a phone or account number in a private message.
