I have been a customer of CitiCard MasterCard since XXXX. I have always paid my bill each month in full. My XXXX bill was due on XXXX XXXX, 2016. They received my payment on XXXX XXXX. When I received my statement in the mail today, I noticed that they have charged me {$23.00} interest. I immediately called them and asked them why they charged me this amount when the payment was received before the due date. The lady connected with me with a foreign gentleman. I explained the situation to him. My daughter explained the situation to him. He refused to take this amount off of my bill. How can a company charge you interest like this? Are they putting these charges on people 's accounts thinking that they will not notice it and pay it? I believe that is unethicial and not right! They need to be reported and held accountable for doing business in this matter!
