Game being customer centric means be diffferent

I have never heard such utterances in my life, my sister n I got my mom home theatres different brands so my mom chose one brand over the other thus needed the one to be returned so we ask her to take it back because we working. My mom then went to game today only to be told that a refund cannot be done cash she needs to bring my sister debit card I'm not talking credit card but debit card because it's the new law for one she paid transport to get and made mention that she had no funds to get home thus asked if they can't help in anyway and she got brushed off by being told that it's the new rule. I mean really if I purchase something with a debit card that's money in my account and when that transaction goes through its paid for cash only using a card and can't be reversed so why make someone turn back for that what happened to humanity looking at an old woman the agent just thought she won't tell me anything including that manager because he /she was also not helpful. I am utterly disgusted by the service rendered to my mom and now know that I will never set foot at that store
