Absolutely no service

My TV stopped working for some unknown reason, so I took it to customer services and explained the situation, and that I do have an extended warranty. They took it and told me it will take about six weeks to fix, which is already ******** in my book because how can you tell me six weeks if you don't even know what's wrong with it in the first place! Three weeks later I get a call from someone telling me the quote to fix the thing is more than R10 000. Then I asked the lady why is telling me this, and she said this is what it's going to cost and when do want to make payment??????!!!! Then I asked how a TV that I payed R7 500 for cost R10 000 to fix, and what about the extended warranty???? Then she said they send it to the wrong people!!?? I was advised that I would get a call within a week. It has been two and a half weeks after that call, and still nothing! So this morning I have been trying to call customer care, and after 4 separate calls, holding on for more than 10 minutes on each call, I decided to give this a try! Makro customer care is an absolute joke!!
