I opened a credit card with Barclaycard Finance in XX/XX/2014 and I purchased a laptop from XXXX. In addition, I purchased little things over the last 18 months. I signed up for e-bills and I do n't use anything but their mobile application. When I log in to see my statements, there are no alerts or anything on their mobile application - just the transaction history. I called the other day and asked if I was on a 18 or 24 month promotional because I could n't remember and I had not received any alerts on the mobile site. When I called, she informed me that my promotional acctually expired and I am about get over {$700.00} in deferred interest. I asked how much of my balance was left and she informed my it was around {$1600.00}. My original purchase was about {$1600.00}. So, for 18 months, all my payments were going to the little purchases made instead of my promotional balances. The extra charges that I made on the credit card were no more than $ XXXX ( bare minimum finance charges that would bill ). I am highly upset by this. I would have rather the little $ XXXX {$5.00} finance charges billed than be billed over {$700.00}. I thought this type of payment hierarchy was against the law, guess not. I guess their take is - Better take care of the little finance charges and bill the customer the big deferred interest and ruin their credit as it will take them over their credit limit.
