Exasperated replacement on warranty client

On 24 October, my KIC fridge/freezer (bought 2 July 2020) from Game, stopped cooling the fridge. I smelt fire, and the back of the fridge was extremely hot, too hot to touch.

After letting Game know and asking for a replacement fridge (as my warranty still stands) they sent fridge technicians from K.C. Domestic Repairs (without appointment, as was stated they had to make one before arriving). They opened the fridge and saw it was cold (there were 2 icebags in keeping it cold for the time being), they left and said it was repaired.

Then I called Game again because I was still having the same problem. They then sent repairmen again from K.C. Domestic Repairs and conducted an assessment, again only opening and closing the fridge. (So far nobody has checked the back of the fridge or tested the condenser or compressor)

Last Friday I called Game again as I hadn't heard anything, with Linton saying he'll check and get back to me, he never did. KIC called me because I left a review on the job site that the service was unsatisfactory, the lady said the case was closed. She was shocked when she heard nothing had actually been changed. So she opened the case again.

Today I called Game, Linton can tell me nothing new. I called K.C. Domestic Repairs, for Yolande to tell me that they have to conduct a final assessment, again. How many times does a final assessment take place, for the same problem with the same fridge?

Also, how does KIC not understand how to assess and replace a simple fridge?

I now sit in the 4th week with spoiled food, wasted money (from buying new food and ice bags the whole time) and an external fridge that packed up in the meantime because I had to overload it with food to keep it cold.
