no installation

On 30/11/2014 purchased dsd4136 at hi fi corp with installation. As I had dstv with old dish wanted to replace but morne the installer said my dish is ok. He delivered dish and was on his way. On thursday 24/9 my dish gave problems error being no signal and showing on screen installation wizard. On 25/9 went to radio sonic in klerksdorp who then told me nothing wrong with decoder but since my installation was so old possibly the cables had given in due to weather conditions so I called the installer morne to come and install the dish he deliverd I'm still waiting.I believe he was paid by multichoice for a complete intallation and he is still obliged to install the dish. I will know it seems have to pay for a call out and I just don't no if ever he wil ever pitch as he remarked that we cannot call him a year later and tell him about the installation. What recourse do I have? Cell phone no for morne is ***
