Wrong product given

Hi We bought an accessory for an Xbox today 15.12 2023 at 09:25 at BT Games Kolonnade. We spoke to the sales consultant Katlego Moema about Xbox Live thats gone and Xbox Game Pass free games. Then I asked for a R250 Xbox gift card. We paid and left. Once we reached home and wanted to load the voucher we saw that we were give a R250 Playstation voucher! I asked for a Xbox not PS. When I phoned the shop they were confused and gave me long stories, told me I must sell the voucher to somebody? It was a mistake done by the consultant not me. I want a R250 voucher for Xbox, I dont have a PS and do not know anybody with a PS. The world is turning to digital, shops like this must focus on the little bit of customers they have, you now convinced me to go digital. I want my voucher, you can have the wrong 1 back.
