Bank of America Credit Card Complaint

Bank of America Credit card department,

Other fee New York

I live in New York - and I have a Bank of America credit card which I used to book my travel -, through - Airways, online. To my surprise, I saw in my CC statement, that BoA has charged me - Transaction fee even though the transaction was in - - as confirmed with - Airways, and as stated in the invoice from - Airways -. I tried contacting the Bank through online chat, through calls and even walked over to the Bank. But the response from them was for me to check the Credit Card agreement which clearly states that the Bank would charge me a - transaction fee. I however, kept repeating that this was not a - transaction since the payment to - Airways was in - and not in -. - of their executives in the Claims department went on to say that because i was flying outside - they consider it a - transaction. Which does not make any sense to me. A - transaction would be one where my Bank would have to pay to the vendor in a currency different from -. That did not happen here.
