Koala T Mechanical Systems Ltd

Water heating regulator was changed but it never worked. I asked for explanation to how it works and got very minimal info. Many questions were not answered. 2nd time, my shower taps and plumbing had to be replaced. The tap handle is sticking 2" out of the wall and hot ,scolding water is coming out first. Quite dangerous with small children. I.was overcharged for the taps set and they refused itemized invoice. Horrible service and work with no accountability. Would not recommend!!
