My Online Profile after Moving Home Service

Hi All,

I have Cox internet and recently moved it from one physical location to another - I rented my home and bought a new one.

I am trying to manage my account online as I have forever, but my account number has changed - according to a call to Cox this is normal. If I use my old login I get a blank screen. If I try to sign up fresh using my new acct number and create a new ID I get random errors. 

Seems like Cox should be able to simply substitute my new Acct within my existing online profile.

Anyone?

Thanks in advance
