I contacted them to convert my jacuzzi to solar

I contacted them to convert my jacuzzi to solar. Jakkie suggested pipes (not the usual solar panels) as he had done this for other clients and it worked well. They three rolls if pipes where installed on my roof. A few weeks after installation I turned on the system and no water flowed through. The pipes had bended and water flow was contricted. I asked them to come fix the problem. I had paid in full for installation if something that was not working. He came to fix the bends. A week later, same thing... now I am being ignored. So I have a paid for solar installation that does not work and he is not getting back to me. Very disappointed. Waste of money.
