Bad customer service

I've been having a problem with my DSTV explora 2a for about a week now. It says "disk full" whereas I had about +-50% used up on my playlist. I can't record nor catchup as this thing keeps popping up, well to my surprise this week it it says "hard drive may be *******. I went to a Multichoice store to report the matter, I was told with a stinking attitude to send it for repairs which might cost me about R600 and that my model is too old, I'm not sure what that meant because I bought this about 2 years ago.
