Payment missapplied / Chat agent contracdictions - Need payment research ticket

Hi,

I am stuck in a billing loop and need some help. Xfinity's system is misapplying my payments and charging me late fees as a result. Attached Images are included

Brief timeline

• 9/17 - Autopay was triggered to my checking account, which was closed as I was moving from one bank to another.
• 9/17 - I went into the app and swapped autopay to my credit card thinking the next time Xfinity would do it it would use this (which i need to change again after learning today the autopay discount is not for credit cards but I digress)
• 9/19 - Payment was reversed to said checking account. (From my knowledge, no actual money was moved since there's transaction history within my Ally account (previous bank), just what I can see through Xfinity transaction history.
• 9/29 - I got in touch with support because I was notified that my payment was late and I was trying to figure out what happened and request a courtesy credit to waive the late fee and credit back the auto pay (once again, I did not realize autopay was not for credit cards but i was not made aware of this by support)
• 9/29 - Received a $15 credit to offset some of the 23 dollar late fee.
• 9/29 - $51.05 payment sent from my Amex to Xfinity.
• 10/1 - Payment reversal of $51.05 to the closed checking account again?
• 10/17 - Autopay triggered for $110.10 to my surprise
• 10/17 - Spoke with support again to figure out what happened and when I asked since I was charged for two months in October, I won't be charged in November the agent said yes, you are correct (attached)
• 10/26 - Spoke again with support after seeing my bill for November was $99. Essentially, I was sent around in circles after being disconnected multiple times. I was billed on the 29th, but it was returned to my checking account ( I didn't know this until then)
  
  That part doesn't make any sense to me. How does my credit card get charged, and then money is somehow returned to a closed checking account? 
  
  I've tried my hardest to be patient with Xfinity and the support team for over a month now, and I'm just frustrated and looking for solutions.
  
  I'm tired of being overcharged again and again when I feel that I've done no wrong.
