Extremely poor service and workmanship from Stark Boreholes

I contacted Ruan to help with my booster pump and irrigation system that was faulty. They repeatedly came in the late afternoons and worked with their phone lights in the dark in the garden. They didn't bring any other lights. Extensive work was done. The situation did not improve. Then suddenly after struggling the whole day, they claimed at 7pm on a Friday evening that everything was sorted out and I had to pay R18 000 before they left. I did so, and then realised that it was even worse that before. The work was sloppy, and looked untidy on top of it. I phoned Ruan and his helper again. They claimed that it was due to other reasons and I had to contact someone that did irrigation, ( as they do not do irrigation) and I should also contact the company that supp**** the water irrigation system that they installed. I messaged Ruan to come, so that I could show him everything that was dysfunctional. He said he would come after work. He never showed up. I confronted him the next day. He said that he would not "help me" again. The whole system had to be replaced by another person. Wasted time and money!! Everything they did had to replaced.
