Poor installation

<p>First of all i would like say that we are highly disappointed by dstv. We bought an extra view decoder with which we received a voucher for full installation. It was arranged that the installer will be here at 9 and he only showed up juat before 11. He got here with no equipment... I am almost sure we were supposed to receive a dish bracket sensor and cables. But none was received.. We were however told that we had to pay extra R350 due to equipment they needed to go buy to do the installation. They left after being busy the whole of sa****ay.. With no success. They returned the following day at 4pm.. And 10min after they had left, again the new decoder stopped working. We phoned dstv and the lady who assisted us assured us that the heartbeat cable is not working properly and was supposed to be replaced.. We phoned the installer and he had a million excuses. When we bought the decoder what did we pay for?? Please advise urgently as i cant believe that a accredited installer can be so negligent in his work. </p>
