Very frustrated about defy and game.

Hi im a very customer who bought a stove like 3 yrs back. Its a defy one and i had a extended warranty for it. The first time it got broken, i called game and they logged a call and a technician was sent to me. Now its broken for the second time and its been a month now it hasn't been fixed. I called game and they said they will send and technician of which they did but they wanted me to pa close to R700. I was and still not willing to pay that money because i have a extended warranty. When i went to the store to find out why on earth do i have to pay out that money to get my stove fixed, the people from game told me that it was no longer under warranty. I have paperwork and proved it to them and they told me it was refunded by mistake. Now that matter got fixed after 2 to 3 weeks. Now defy is super to send a technician but they telling me about the driverd car that broken. Apparently he was supposed to come to me house and fix it. I did a follow up and they taking me from peter to post. It comes out that the part of the stove is burnt and they can come in tomorrow but i have to pay R50 because the warranty doesn't cover it and more stories about the driver. So im sure it will take another 21 days to get my stove fixed because we going to a national lock down.
