GameStop review: Game code had already been redeemed

My daughter purchased a digital code game for $30.00. Upon opening and trying to download the game, she received a message stating the game code had already been redeemed. She contacted the store which directed her to call/email the customer service link for a new code. She got nowhere with that direction, so I accompanied her back to the store to either get a refund or a credit for her out of pocket cost. The young lady at the desk proceed to tell us that there wasn't anything they can do, including reimbursing her the cost because she does not know if we gave out the code to someone else to use, "REALLY" (what sense would that make, if you bought it to play it)! I responded maybe an employee took the code and closed the case back up. She stated that it is not the policy of the store to reimburse for digital games, I asked her why are you selling them, I consider it defective. I asked for the store managers name, which she refused, I also asked her name because her badge with turned over. She refused to give me the managers name but offed to give me the corporate number. I asked her for a pen to write down the information, she replied she couldn't because of COVID! and asked me to leave the store or she will call the police. I told her go ahead, I'll be waiting for them outside. Once the policy arrived, I explained what happened and he went in and got the information for me. The employee name is Fiorella Holness and with employees like that you will always lose business. I am requesting a refund of the monies paid for a game that is useless.
