Appalling service from Plumb Ambulance Pretoria

I had a burst geyser at home in late April. Plumb Ambulance Pretoria was contracted by the body corporate through their insurance to attend to the problem and they eventually replaced the geyser. Within two days, the geyser was malfunctioning with the water not quite heating up and if it did the water would be cold after one person showered. I called plumb ambulance and they wanted to charge me a call out fee of R900 for a job that they were supposed to do properly in the first place. After some back and forth they came to look at it but the problem never went away. Now less than two months from initial installation, the geyser trips and we do not have hot water in this chilly winter weather. Zero customer service from plumb Ambulance Pretoria.
