Bosman Plumbing Constantia: zero value and abysmal customer service

I would never use Bosman plumbing (Constantia) again. They arrived, heard exactly what I told the woman when I called, said they couldn't help and recommended getting a leak detector. Then we got a bill for R780. When I queried what we were paying for, I was told multiple things that were flat out wrong (like that I had been informed of the call out fee -- nope -- that they had rectified the problem -- nope -- and that I told them the issue was a faulty valve -- nope, because we had just replaced it!). From there, they brought up threats. Zero value and abysmal customer service. I mistakenly called this company rather than Clyde Bosman (Lakeside), who have been great. I won't make that mistake again!
