Product: Credit card

The credit card regarding this complaint is with BankAmericard. We received a balance transfer offer with this card which we did use back on XXXX XXXX, XXXX totaling {$8600.00} plus their transfer fees. We took another offer on XXXX XXXX, XXXX totaling {$3100.00}, plus fees. Their fees are XXXX % of the transfer amount. The first offer had no finance charges/interest until XXXX XXXX and the second offer we took in XXXX XXXX had no finance charges/interest until XXXX XXXX. Those XXXX transaction dates were the only ones. On XXXX XXXX, XXXX I received my monthly statement and noticed a balance adjustment posted to my account and it listed it as a check cash advance. We immediately contacted the company and first spoke to XXXX in customer service for almost 50 minutes while she tried to figure out and try to reason with why they have that on the statement. While researching this transaction, we found out that they did this several times on our monthly statements ( 8 previous times is the only information she could provide because she only had a certain look back period ). Since she was flustered with this call and not being able to explain how corrupt the transactions were, her supervisor XXXX came on the phone. Both representatives were located in the XXXX PA call center, since I asked for their Bank of America ID # they would not provide me the information. Here is the issue : every month we make payments to the card and always make MORE than the minimum payment each month. They told me that the reason I see on the statements a transaction of a check cash advance is because they have to MANUALLY APPLY MY PAYMENT TO THE FIRST PROMOTION DONE IN XXXX XXXX. Being in the legal field I would think maybe that my statement should NOT state that I took a CHECK CASH ADVANCE, WHEN WE DID NOT. 
Second problem Bank of America has an added additional amount to our second promotional offer. The second offer was a total of {$3100.00} in transfers plus the XXXX % fee. The balance on that offer should still be the {$3100.00} plus the {$93.00} transfer fee they charge totaling {$3200.00}. Now since this account is not accruing any interest yet, and no payments should be posted to this account yet since they should only be applied to the first promotion, how could they explain that they show I owe {$3200.00} on the second promotion? There should only be a current balance of {$3200.00} leaving an overcharge on our account in the amount of {$62.00}. Does n't seem like much, but if they do this to all their customers, it will add a profit to Bank of America, illegally. Since this is the only error I have caught so far, I will need to revisit all my statements from the time we opened the account and calculate the payments against what we initially borrowed. The supervisor XXXX had some crazy explanation that made no sense and I would invite anyone to listen to the recording of that call, which I asked to make sure that the call was being recorded. Please investigate Bank of America card services to see if there is some explanation they could provide that makes sense how they added additional debt to our account that we did not use. I have a current statement for your review if needed.
