Poor and Horrible Service

I bought the decoder with the intention to add the ExtraView and save cost. Little did I know that I will end up spending more. After purchasing the decoder I then called an installer to add the extra view for me. I was made to purchase the smart LNB, which I bought and they installed and payed, It worked for 6 hours and Error E143 -0 popped up, Called DSTV and told me that Is was an installation error. I called the installer to recheck and said there was nothing wrong. I got the second installer who came and installed using a di-plexer , removing the newly purchased Smart LNB. Payed the second installer. Again it played for about 6 hours and error appeared again. Called the DSTV again they refereed me to the "ExtraView Specialist Team". They gave a call and suggested I take the decoders for testing, I did that , no problem found. I came back to the same problem. So desperate for it to work. Called the 3rd Installer, came and check and said everything was perfect, he sees no fault. When we called the customer care they had no solution even with the installer still on site. I really do not understand that 3 different installers could fail to fix one issue unless it is an error from DSTV, which they fail/do not want to knowledge. I have paid every installer who came to fix and still no success, Call Agents useless as ever. Extra View Team the worst, I do not even know why they are called specialist. To add to the frustration I then decided to separate the accounts, while I was still enjoying viewing boom the so called "ExtraView Specialists what what" disconnect my services without my concern. I have been billed for the service I never used and I have received poor and terrible service from the DSTV team as a whole. Very disappointing. I dont know why you keep promoting something that does not work .
