cable card issue

I just spent two hours with support.  My bedroom tivo, which has had a working cable card for three months (I was forced to get new cable cards when I moved), suddenly stopped connecting to xfinity.  So I was getting a V58 error.  My main Tivo is working fine. 

Upon speaking with a service technician, after doing the appropriate things like unplugging, and rebooting the box, etc, they finally sent me to the "cable card" department.  I was informed that my second cable card was removed from my account, without my permission, and even though they tried adding it back in, they found they could no longer authorize a cable card.  No one could tell me who authorized the removal of the cable card from my account (it wasn't me), nor could they replace the cable card.

I have been a Comcast customer for at least 30 years, and am really angry that someone just decided to remove that card from my account. 

I understand that Xfinity will no longer be supplying the cards, but I was not aware that they would no longer support the cards that were currently in place, and would be removing them from accounts.

I think it might be time to move on from Comcast to a different cable service.
