DSTV Connectivity

I have to say since we received our DSTV decoder - if out of two years we have had 1 year full screening with no problems what so ever its is a lot .... our DSTV keeps on telling us there is a fault in the installation - no network or just doesn't work - the scrolling function freezes - nine times out of 10 our package seems to not cover or display the channels that we are paying for - and then to top it all off all the blady ads - our DSTV has not been working for about 4 days - my next payment is due by the 1st of September - why am i paying for a service that i am obviously not getting!!!!!! And if I Have to hear that I must reboot my decoder or pull the power supply out or take the card out once more I might just have a heart attac****!
