I find this very puzzling. HRO policy is to charge a 15% restocking fee on "non defective items returned . . . . ". You did not return anything?? It appears, if what you state is accurate, that they are not adhering to their own policy. Seems to me you should be talking to the manager about this. Something may be left out of this story . .. .
