Gets mad at me for wanting a refund within 2 days

I bought an xbox 360 wireless receiver from them on 02/01/16 and it does not pick up on any PC i plug it into. I took it back on 03/01/16 and the manager complained about a sticker that was not on the item anymore. She took a new one, that didnt have a sticker on either, then put a sticker on and gave that to me. I went home to get the same problem again. I took it back withing 30min for a refund. The manager then wants to give me in-store credit. I asked for my money back and she went off on me saying \your being difficult. I do not want to talk to you"I insisted on the cash back and she eventually gave me the refund back on card after getting so much lip from her.<br> <br> I never ever had such bad service in my life. No one should ever have to go through that. Dont buy there"""
