Poor service

I purchased a fridge on black Friday at game last year , since then the fridge has been giving problems, I logged a complain and the technicians were sent to my house, the problem continued and another technician was sent for the second time, recently the fridge stopped freezing I went to the store last week Monday,, I was told they cannot get a hold of their supplier (hisence), I requested to speak to the manager as I want a refund was given excuses with regards as what has to be done to follow the correct procedure, this whole situation has caused me a lot of money as I had to throw away everything that was in the fridge, this is the second week, they haven't phoned to let me knw what's going on. I will never ever buy electric appliances from game,,, and their service is very poor
