DSTV Im out

I went to a walk in centre to swop my explora2 decoder as it had a fatal hardware error. As i dont have insurance i paid R600 for refurbished decoder. It worked 1 day and had the same fatal hardware error. Back to Hi-Lite Audio and was told they dont have anymore stock, I should phone everyday to check for stock and if they do have stock i shoulld jump in my car immediately as they cant keep stock!!!!!, Noting that i actually have a full time job !!!!! Without calling a week later i popped into the store to ask for a refund, as i didnt a) want to deal with the walk in centre, and b) i dont have the time to keep travelling 40kms return trip. I was then told they have a Explora2 in stock and I cant get a refund ??? I took the other refurbished decoder, went home plugged it in it worked for 30 minutes, reset itself and has been loading for 36 hours !!!! called the walk in centre and was told I must get the refund from DSTV as the R600 gets paid over to them directly, called DSTV, sent 3 mails and have been told that i must get the refund from the Hi-Lite Audio, who refuses to give a refund.
