Bad service from Makro Germiston

I bought a Hisense fridge from Makro Germiston on Saturday the 25th of May and bought it cash. On Sunday the 26th I realised that the water dispenser is licking. On Monday the 27th I called the store and told them about the dripping water from the dispenser. I must say the guy who assisted me was quite helpful as he organised for the fridge to be collected the next day Tuesday the 28th and a new one was delivered. But on Wednesday the 29th I realised that new one which was delivered doesn't get cold. It's as warm as ever in this winter season. I called Makro Germiston on Thursday 30th and spoke to the same guy who assisted me and he remembered me very well. He was a bit disappointed at the fact that I was given another faulty fridge, and this time said he would refer me to the guy that sold me the fridge to deal with this issue. He promised that the salesperson will call me back so that this issue is dealt with. I never got a call back from the salesperson. Now the fridge is licking some water not sure where it is coming from. And all the meat and food in the fridge is now spoiled. There's now even blood at the bottom of the freezer which comes from obviously the meat. I am very upset at the fact that 2 fridges which were given to me are faulty and the store has not taken this matter seriously. Having said that, I have the unnecessary work of having to clean up the mess the fridge has created for me. Also the money wasted on food which is spoilt and cannot be eaten. I am very frustrated as well as disappointed on the service delivery I have received from the store. I now wonder when will this fridge going to be collected and I am not sure if I still want another one delivered after this bad experience from Makro.
