Poor after sales service

Plus minus two months ago I discovered droplets of water running down the inside of my fridge. I called Russell's and was told that a Technician would contact me to arrange inspection. A week passed and I had not heard from Russell's/technician. After I called Russell's for the second time, in about two days I was contacted making an appointment for two days later to inspect my fridge. When the technician arrived and did his inspection, he concluded that my thermostat was busted which he replaced. Two days down the line I noticed that the problem was not eliminated and called Russell's again. This time I was asked by them to call the technician myself which I obliged and after another week still no sign of the technician or Russell's. I called once again and was asked to call the technician again which I refused exclaiming that it was Russell's to and after another week the technician appears at my door, does his inspection and concludes that there is an internal gas leak and that it would be best if the refrigerator was replaced. Another week passes and I call Russell's and they spin me a story that I refused the technician to work on my fridge. My fridge is still problematic
