DISGUSTING DSTV SERVICE

Good Day. Today I am really not happy with DSTV. When we relocated our DSTV HD was ****** thay was a year ago. We had to purchase a new DSTV. We've had several problems with DSTV getting errors saying our subscription is being checked. This went on for months. After several calls of fixing the error we were told to take the decoder in because it might be faulty. My husband took it in today to check out. Now he's being told that (the one we were told a year ago was a new type)should be replaced. And at a fee of R250. How is it that we should pay for a new decoder when we were told it is a new decoder? How?Whe had our DSTV HD for many years and never had thos problem, unfortunately it was ******...but the new one is faulty and we should replace it at a fee. When we phoned in to DSTV customer service to find out why we need to pay for a new decoder because it is still new, the call ventre agent said we shouldn't ask them as it is a call centre, rather ask the store why we should replace it. This is bad customer service! DSTV can't even give us a decent explanation now we are liable to pay for their faulty decoders....Does it mean that we should pay a fee every year?
