Violation of my consumer rights

<p>2 channels on my HD decoder is not working, DSTV claims that this decoder has been discontinued therfore they cannot update, repair or swop it. Their solution is for me to exchange it for an Explorer decoder at an additional cost of R1200.00. I am therefore being forced to purchase a decoder. This is unexceptionable, I am a premium subscriber with extra view, paying for these channels and I expect to view them. When I purchased my HD decoder and signed up for a Premium subscription this was not mentioned and was not a condition of acceptance. DSTV misrepresented the sale of this product resulting in a clear violation of my consumer rights</p>
