In XXXX, I purchased XXXX sweater from Bloomingdales for {$22.00} and used my Bloomingdales credit card for the purchase. The payment was due on XXXX XXXX. I made the payment today on XXXX XXXX ( 5 days late ), but I found out that Bloomingdales had assessed the interest fee of {$24.00} on the ENTIRE balance on the card, {$22.00} of which was late and {$310.00} which was NOT late and current in the new billing cycle. When I called them, they were unable to explain why the fee was assessed on the entire balance including the non-late purchase and were unwilling to re-calculate the interest. It is predatory to charge me an interest rate on a portion of the bill that is not late, especially when that interest fee is MORE than the amount late -- it is usury in it 's classic sense.
