Bank of America Credit Card Complaint

Bank of America Credit card department,

Billing statement Illinois

I have a credit card from Band of America and I set up the automatic payment to pay my balance fully every month. But when I checked my statement, I found that from -/-/2015, every month there would be multiple payments to my credit card. One is called PAYMENT DIRECT DEBIT - THANK YOU, the other is BA ELECTRONIC PAYMENT. and in most of months, the combination of these payments would exceed my balance, which led to a credit balance in my account. I just called BOA and the customer service said one of these - payments was not recognized. But I only set up the automatic payment on BoA website. I did n't set up other automatic payment.
