Not the greatest plumbers!

The service was very bad, the plumber did not explain what he did properly, they were supposed to replace a 0.5m piece of pipe that was leaking from the hot water section of the geyser that the previous bad plumber put in that could not take the hot water, so it started warping and leaking. They replaced that section PLUS the copper pipe section with another pipe that supposedly can hold the hot water. They took my copper pipe without asking me first - isn't that theft?? This was not a claim from insurance but a private job that the plumber was well aware of. I would not recommend these plumbers to anyone.....
