Need issue resolved!!

When I signed up for xfinity mobile there was an issue activating my account because you did not associate my Mobile number with my address (I have internet services). I spoke to someone, was told it was resolved, and setup recurring payments. 

Since that time I got a new debit card. 

I am not able to update my account, am unable to reach an agent via phone, and keep having to describe the issue over and over on your online chat without resolution. This is unacceptable!!!!! You have cut off my mobile service and I do not have the option to pay my bill!!! Your online support puts me in a frustrating, endless loop! I’ve explained this issue to 10 different agents and have now spent hours on this!!!!! Please resolve!!!
