Can't access my account after moving

@user_1a5b5f 

I moved my service to another address recently. Service is working fine, but I can't access my account from either PC or my mobile app. In PC (mac), when I chose billing option after I logged in (log in works here actually), it shows infinite black screen. Mobile app says my service is not available from the (probably previous) address.

When you move your service, even if it's just next door, you're assigned a new account number.  Chances are, your old log in won't work unless you made sure that in your transfer all information would transfer with it, including your email addresses.  It's a frustrating glitch that Comcast doesn't get right from time to time, and you're "caught" in that time, it seems.

Check your Primary username [it may have changed].
