Access Not Authorized - You signed in successfully, but you must be an Xfinity user to enjoy this service. HELP!

I signed up via the web for Xfinity internet today. I was so excited, but this has been nothing but frustrating and disappointing. I have a new Motorola Modem/Router MT7711 that I am using. I followed Xfinity and Motorola's instructions to set up the internet in my apartment. When it came time to activate my internet I did as instructed and downloaded the Xfinity app, but when I log in it says, "Access Not Authorized - You signed in successfully, but you must be an Xfinity user to enjoy this service." I am an Xfinity user and the account holder. I checked my account on the Xfinity account app and it says you no longer have Xfinity service at this address. How can this be, I have paid and signed up?!

The modem/router is working, but there is no internet. I have called several times to the 1-800 number with promises they will call back and will escalate the situation. I had to switch from ATT because of the new area and this has been nothing but trouble. I never had these kind of issues with that carrier. I just want the internet that I am paying for to work in my new apartment. I need help as soon as possible.
