Ever since my monthly charge went up $40, I’ve had issues with Xfinity not handling my ACH correctly.

Xfinity refuses to paper bill my account, so I had to set up an ACH account for them to draw on. My billing amount was transferred each month. But when it went up a whopping $40 and they notified me I the worst possible way (my email account that is super-spammed), I did not find out until 2 months later. I got the account current by paying within the app. Now it says I am past due again, and won’t go through the autopay/ACH. I need to speak with a PERSON, as automated AI cannot deal with my specific issue. Please help!
