It is possible that what you are writing is correct, but I seriously doubt the veracity of your story. I have dealt with Comcast on modem issues and they either will gladly provision the modem or will not provision the modem for very good reasons. One reason for not provisioning the modem is that it is registered to an account that has billing issues. I suspect you know that this is the problem.
