Can’t Access New Internet Plan

Returned Comcast Modem to replace it with a purchased Cable Modem Router. Xfinity rep changed my plan to account for this while adding a code for me living in the same place for the next six years. 

My auto payment method was deactivated. They said I had to re-add my payment method. Went to add a payment method and the app says I don’t have access to that. I am the only person on this account. If I don’t have access then no one does. Made a one time payment ahead of time and that worked. Auto-pay shows as activated in settings, but under bills it shows as deactivated. 

When I try to activate my Cable Modem Router the app asks me to activate a plan. The rep at Xfinity already activated the new plan, so I don’t understand why it isn’t updating my account info except to show the old plan was deactivated. So now I paid early for my existing plan which is now failing to provide any service, and the new plan is not showing up at all. 

Yes I tried restarting the app multiple times. Signed out completely several times. Yes I called the customer service lines with their useless bot. Comcast is the only ISP I have ever used. I need an actual human being to help solve these problems.
