GameStop review: Will not accept item for refund

Copy of an email sent to your customer relations.

To whom it may concern. Recently purchased expansion hard drive. Was sold wrong drive (Not compatible).
Here's my experience.
Visited a game stop, with my grandson, for info or purchase of expansion drive for Xbox series X. Walked into your store in Southington CT (store # 7651). Not knowing what was needed, i asked the salesperson if he knew what we needed, his (condescending) answer was, "I work here don't I". Letting the attitude go, we told him what we were looking for. He indicated he knew, reached behind him and said, "you need this". after a few efforts my grandson couldn't get it to work. (He's 18 and knows his xbox). He returned to the store without me because i live an hour away. The people in store said he couldn't return it because it was opened. 1st, your "expert" employee, who by the way dresses like he lives out of a car, is the one that pick the drive. NOT US. 2ND, how could we know it didn't work without opening the box?
I conversed with them over the phone (Remember I'm an hour away now) and was put on hold while they called the DM (Nelson), who also said we could not return it. They gave me a "support" number of 877-610-7529 and hung up. I called. Had to speak with a foreign accent person that i could barely understand. She gave me a reference #, 232351, and said I had to call this number from the store so she could speak to the salespeople. I gave my Grandson the info and asked him to go the next day to straighten it out. He called me with, not surprised, a no results message. Turns out when he gets to the store, there's a note on the door, "On Break back at 7:15PM". he waited and when they returned, more of the same nonsense. He called the 877 number, was disconnected and had to call again. Your people spoke and then your employee called his "DM" with the same result. Do not refund the money. By the way, we're talking about $100. My Grandson called me with the ridiculous news.
Can someone call me, [protected], to rectify the situation. this is the second dealings with Game stop. The first was almost as bad. So please do not recommend a store credit.

Will someone with common sense return my call.

Frustrated, soon to be non-customer

PS, left a call back request at your corporate customer service number. I either get a callback from someone with such a thick accent I can't understand them or after they hear my problem, they put me on hold, then the call is dropped

HELP!
