My Xfinity Account Records are a Mess (2nd Try)

15 months ago, I relocated from one home to a new home in the same city and transferred my services to the new home.  Somehow, the old account remains "active" and is set as my "default."  I can log into the account with my old username and password.  Since the balance is zero, I received no bills or anything else.  On my "new" account, I also can log in.  But logging in does little: no actual account information is presented.  I can also log into Xfinity Stream from my PC, but it does not function: no TV listings or any other options are available.

How do I --- or more likely Xfinity --- finally fix this problem??  BTW, my large $$ paper bill never misses a beat arriving at my home.  (NOTE: I have already posted this once, and responded to XfinityChristy with a detailed DM.  No one replied.  So I am trying AGAIN.
