Greetings, and thanks for reaching out to us on the Xfinity forums, I hope this message finds you well. I am sorry to hear that you have closed your account, but you have come to the right place for assistance with the billing. When we set an account to close, it is usually set out a bit to allow time for the system to process, but with a billing end date of the date that the account was requested to be closed. Once the system processes the order, it will back date the billing to reflect.
