Worst service by Mpho Game southgate

I had the worst experience with Game Southgate. My sister bought a Bennett Read 28l microwave on the 1st of July 2023.Within a period of two months the microwave was no longer functional, it was not warming the food. I returned the item back at Game around October 2023 and was told they will book it in for repairs (how do you repairs something that is still new).It was repaired and I was called to collect it around beginning of November 2023. On the 10th of December the problem started all over again. I went back to the store on the 13th of December with their product and spoke with Xoli who advised that they will refund me within 24 hours. I asked for a new microwave on the same day and she called her manager by the name of Mpho ( fat and short lady) who told me she will ask for refund on my behalf and rudely said Game did not invite me to come buy at their store as I was asking for a new microwave. She went on to say I must google the terms and conditions of 1evo product or call them so that they can refund me. To this day I have not heard anything from Game( Xoli and Mpho). I just want game to give me my money Ill go where they value their customers since Game Southgate branch don't.
