Hello, Kneistat. Thanks for reaching out to the Xfinity Forums with your concerns.
We understand how it can be inconvenient, but all outstanding balances must be paid before a past customer can re-start services. Once the balance has been paid, we would love to help you find a new service plan that fits your needs for the best price possible. When you are ready to re-start service, send us a private message with your first and last name as well as service address so we can assist.
