A bank not knowing their own costs/calculations/charges?

<p>By my 4th call I still did not get what I would get charged once I paid up my Credit card at the end of this month. </p> <p>I want to keep my credit card even tho I owe nothing on it, now I just need to get how much I will pay monthly on no outstanding amount. But the consultants cannot tell me even tho I try asking the question as simple & direct as possible. People in need cannot afford 4 calls, so how deep does this rabbit hole go.</p> <p> </p> <p>Maybe just best to close my account and take my credit card to a normal bank.</p>
