Secondary Decoder not working

Nine days ago our secondary decoder stopped working. I phoned dstv to report the problem and they told me it was a software problem and their technicians were working on the issue. Our case number is *** . Despite calls every day and assurances that the problem is being addressed , we still have no dstv on our secondary decoder. The responses are the same each time we query the progress on the problem. They are working on the software and the technicians are unable to give a turnaround time. The issue should be resolved by the end of the week! The end of the week? WHICH week is dstv referring to? Last week , the previous week or next week? No-one is able to answer my queries. Time for an alternate supplier of cable tv in South Africa. Dstv has the monopoly and they know it .
