Multichoice is the worst!

Last month I had a problem with my Explorer, a lot of channels had an error. I phoned multichoice call centre where I was advised to take my decoder to the nearest branch, and I did. They checked it and told me that my decoder is faulty and I have to buy a new one and I did, the price was R699. I went home with high hopes, I experienced the same thing with the same channels that were showing error. I phoned a call centre where I was advised to call a technician. The call out is R350. Only to find out that my old decoder doesn't have a problem and it's 100% working, it's only the LNB, another R350. Thanks to multichoice. If they had someone who is technical minded this wouldn't have happened. Everything about multichoice is going south, programmes is nothing but thrash. Repetition of old thrash.
