US consumer satisfaction with credit cards plummeted in 2009, driven by anger due to fees and higher interest rates, according to a J.D. Power and Associates poll released yesterday. The poll showed around 20 per cent of customers reported an increase in their interest rates since 2008, with the largest decline in satisfaction among revolvers, those card holders who carry a balance from month to month. In addition, 18 per cent of customers complained about various fees, up from 10 per cent a year earlier. The customer satisfaction index fell seven points to 703 points on a 1,000-point scale.
