Very poor customer service from Ad-Hoc Plumbers

The worst plumbers I've ever experienced. They came to my house to do a burst geyser assessment for the insurance. They changed the story that the issue is with my solar panel installation and that's the reason that it burst. I disputed their analysis as I've had the solar system for 4 years now and the geyser was already 8 years old. To make things worse, they took five days to submit the report to the Nedbank Insurance, while my family haven't had hot water for a week now. Ad Hoc Plumbers do not deserve to be called plumbers
