Business and Management Big banks and cable television providers traditionally receive very low customer service ratings. Many of us simply hate dealing with banks and cable companies. In a recent survey by MSN Money, each participant was asked to select the one item that matters the most in customer service.11 A random sample of consumers was obtained shortly after the 2014 holiday shopping season, and each was also asked the same question. The results are given in the following table.
