Autopay Broken

I have used autopay with Xfinity for over 5 years. Suddenly, it has consistently been broken for the last three months. For the first two months Xfinity support gave me lip service. Today I was told my card was declined by the payment processor (CALL). I contacted my bank. They have never seen any of these payment attempts from Xfinity. The payment being declined is an error because the bank reported there was never any attempt made for it to be declined. I then made a manual payment with THE SAME EXACT CARD and it went through no problem. The autopay system is broken. Xfinity seems to be ignorant of this and chooses to ignore the issue. I don't want to do direct payments from my bank account FOR OBVIOUS SECURITY REASONS. Xfinity has had multiple data leaks in the past. I can cancel a card easier than I can move my savings into an entirely new bank account.
