Angry customer (poor service)

2021 Around May i bought a stove at Game Canal Walk and by July the stove was defected, one plate stopped working and the other got slow. I then returned the stove to game and bought another one, 8 months later the stove also got the same defects (one plate not working and the other heating up slowly). Both stoves broke in less than a year and having the same defect. I spoke with the manager (Quinton Jaftha) and he ended up fighting with me verbaly as I was requesting my Refund beacuse they have sold me two s****s in less than a year. I then gave in and let him book in the stove for repairs and waited 3 weeks for the stove, till today i am still waiting. i started sending them emails and that's when i got a call from the manager (Quinton) and told me that he will call me later but never got the call. I then called him 2 days later and ended up having another Verbal fight with him cause i resquested that he refunds me because i have been waiting for the stove for 3 weeks and in the procces it's costing me money as i have to start buying fast food. I then told him that it is imperetive that i either get a reliable stove or my refund as my family is coming back and I cannot feed my 3 year old fast food every day, he then told me that i must do what i need to do and then hanged up the phone on me.
