Care Credit / Sychrony Bank Care Credit Charging Incorrect Fees and Wrongly Credit Reporting Internet

We have had Care Credit for two years. For the first year we paid our payments over the phone, then the second year we changed to auto payments where the payments would be automatically deducted from our bank.  Twice Care Credit took us off autopay and charged us late fees and interest saying it was us that canceled the auto pay.  The last time, we made a big payoff of over $800.00 to pay off Care Credit.  Not knowing we were short $80 to pay it off, it left us a balance of $80.00 in the account.  Instead of Care Credit taking it out of the bank account, since we were still enrolled in auto pay, they took us off auto pay again and charged us over $100 in fees and reported us to our Credit Report.  We called Care Credit and spoke with a customer service agent on 12/2 which acknowledged their mistake and he removed only $75.00 of the fees.   We called back today on 12/5 after seeing it was on our credit report and spoke with another agent.  The agent was dismissive and rude, saying we were never on auto pay, and they they report correctly, and that he would not remove it from our credit report.  For two years we paid them on time.  And twice they took us off outo pay and charged us fees.  Twice it was they're mistake.  Now they reported us to credit reporting.  And they refuse to do anything about it.  They rip people off, charge fees, and offer no assistance, and stick it too you in the end when you pay them off!
