Owner of the business doesnt want to be involved after third request to get involved.

I called Rain Irrigation to do a re-installation. They came out and checked what needed to be done and sent me an estimate for 13K, ALL OF WHICH MUST BE PAID UPFRONT. They sent a gent out who did the re-installation one of the circuits then after they left leaked profusely. They sent the same person back who said the one faulty circuit was stuck causing the leaking. When I a day later wanted to show my gardener the system that same circuit doesn't work at all. I called Mr Oosthuizen back and he said he would send the same guy out again, BUT it probably wont be this week. Moral of the story, if asked to pay 100% upfront move on.
