Useless

I have a premium subscription with dstv and am extremely disappointed with their service. My problem lies in the sense that I had my dstv reinstalled 4 months ago. I saw, when I started viewing dstv, about 12 channels didnt work. I didnt think to much of it because the Error code read, that the problem might be due to bad weather or a faulty connection. I tried sorting the problem out myself but to no avail. I then contacted them via email as my cell signal is bad where I live. They were quick in responding but told me basically to do what I had already done. I mailed them back and told them that the problem was still persisting. They then responded by saying I should take in my decoder and get it tested. This is unacceptable I live very far from any urban area so to travel anywhere is a problem. I am also in the hospitality industry so we work long hours and dont have weekends like others. I refuse to drive in (paying for petrol and maintenance on my vehicle) to a city to get my decoder checked just for them to tell me nothing is wrong with it and then have to pay them to test my decoder. I am already paying full price for their service but am not getting what I paid for. I am really unhappy with the situation and the way that the conversation was left. I pay a lot every month and I am not getting the full service.
