Disgusting service

I bought a hair clipper at game. I only used it thrice. When my son wanted to use it again. He find out it is not working it is just messaging the head instant of cutting the hair. I bought this clipper between June or July. Unfortunately for myself I misplaced the receipt. When I took the clipper back to Game at Cape town the flately refused to take the clipper without receipt. While I was queuing, there was a lady returning globes without a receipt and they assisted her but they failed to assist me without a receipt. And there was a guy returning the same clipper behind me but fortunitely for him he got the receipt. I think there is a problem with the clipper how come two customers the same time returning the same item. It is worse I went to store manager Louis he was not helpful at all. I lost the receipt because it was not my intentions to take it back. I am taking back the clipper because it is faulty.
