My question involves a consumer law issue in the State of: Michigan
My mother in law gave my husband and I a 40" tv for Christmas, it was defective. She had purchased it online at (a famous warehouse store). She emailed me the invoice receipt, (the invoice that was sent to me didnt have the cost listed on it), and I went into the local store to exchange it. They looked up the receipt in their computer and told me I could either get cash back or an in store credit for $937. I told them I wanted to look and see if they had a comparable tv there in the store, and if so I just wanted to exchange it. I found a 42" for $699, and since I still had a credit left, I picked out a tv stand for $198. When I went back up to the desk the associate pulled up the info, and even had another associate, Im assuming a manager come look at it and they finished processing the in store credit. We left the store with our merchandised very pleased that we had gotten our tv replaced for the defective one. We went home and immediately started to put together our new tv stand (which took 3 hours to assemble). We were very pleased with our new products. This all took place on Tuesday, an associate from their store called me today, Friday. They proceeded to tell me they had made an error and refunded us too much on our exchange by $400! Then they told us we had two options, to bring the merchandise back, or to pay the difference. They had also called my mother law, who made the original purchase, and told her that if this wasnt resolved, they would block her membership. They also never told my mother in law that they were the ones who had made the mistake. I feel like we are being accused of doing something underhanded, when we clearly did not do anything wrong. Why should we as the customer be inconvenanced by their mistake. We had no idea what the cost of the tv was, and we clearly stated it was a gift. Can they legally force us to return these items? What about them blocking her membership?
