Worst service

I submitted a geyser claim & last week recommended plumber cane to replace our solar geyser. The geyser was installed & replaced successfully. Few days down line no pressure in hot water and no hot water. Reported again to insurance and same plumber was sent after we did not have hot water for 2 days. They couldn’t resolve as they needed a certain spanner. They came again today and left us in the same situation now but with pressure but no hot water. Tried calling plumber to no avail and insurance. Worst service in my life. What we see on TV is opposite and that said will be cancelling my insurance with Outsourance. Very ☹️ Disappointed ☹️
