How much longer do I need to BEG for assistance? Is a month without a fridge and freezer not enough?

5 Days short of a month without a working fridge or freezer... On Saturday the 9th of April I phoned Hirch's Centurion to let them know that my Defy fridge that is still under warranty is making strange and very loud noise, the person on the line could actually hear it over the phone, that's how loud it was. She informed me that they have a 72 hour turnaround that will start from Monday as the next day was a Sunday, I thanked her and so started waiting. On the Wednesday the 13th of April I received a call asking if a technician has contacted me yet to which a rep**** no, I was told that they will find out what is going on and let me know. On Friday the 15th my partner was contacted to find out if a technician has contacted me yet to which she also rep**** no and once again we were told that they will find out what is happening and get back to us. On Monday the 18th April I get home to a freezer that has given in and all the meat in my freezer has defrosted and started gong off. I immediately contacted Hirch's and informed them that this is absolutely unacceptable and that I have lost almost R2000,00 worth of food and I expect to be compensated for this and also to have a technician at my door first thing in the morning, knowing that they open at 8:30am, On the 19th April at 10:15am a technician called Abdul phoned and was at my house at around 11am, he said that there was a gas leak and it is a specific type of gas that he will have to go get and that he will be back later that day, he phoned at 18:00 and said that he will come the following day, he did not, he came the following day and re-gassed then said that he also now needs a fan and will come back with it, he did not, the day after that he came with no fan and checked the gas leak again and had to fix it again as it was not done properly the last time, he then remembered that it needs a fan and promised to come back. During all of this I have phoned Hirches continuously to the point of exhaustion. All they do is blame DEFY What more must I do? How many more days must I try to take off from work? How many more days will I be without a working fridge or freezer? How is this just ok????
