Worst, most horrible customer experience ever

I have had the worst experience with dstv.,wait correction, I am still having the most horrible service ever.... I have not had a TV on in my house for the past two months with out my picture disappearing.... I have called in on numerous occasion spending countless, meaningless hours, spending thousands and yet I get sent around from pillar to post.....i was told initially dstv had a satellite that "broke" and they were sorting it out, I then called and it was sorted but then my picture was gone.... Mind you this was two months ago.... I was then told I had to bring my decoder in as dstvs problem was sorted... I did so.... They checked it and it was fine got home and still no picture...I was then told I had to get a newer decoder for my extra view as it was old... I did that and still no picture... I was then told I had to get an installer in.... I did this aswell.... I rewired my whole setup and still no picture.... I had the installer chat to dstv already... Both decoders play channel 100 and the rest of the channels tells me it's not on my package..... I am so fed up and don't know what to do any more... I have spoken to a number of team leaders requesting some one to call me but no one gets back to me.... Dstv is the worst service prouder and has the most *********** ppl working for them.... I was once told by a dstv representative that I was **** to just to get me off the phone.... I am exhausted and about to cancel my subsctibtion and I would never recommend it to any one
