Letter: Maddening music

Sir: It is infuriating, when trying to do business on the telephone, to find oneself left listening for minutes on end to an idiotic musical- box representation of Mozart or a foxtrot played by Glenn Miller. I suspect that irritation with this practice is almost universal. So how can customers convey their displeasure to the many companies that use this device?
