No response, delivery or sticking to promises from TechniCool

I see one good review and one bad review already on Hellopeter about this company. The one good review I can promise you is probably the owner of this company. The other (bad) review is spot on with my experience. First they promised a date for installation. Then they moved it on and said they will be there first thing to install my 3 aircons. They pitch that day at around 15h00, intalled half of what they needed to, damaged the fins on one unit and installed one indoor unit skew with a hole sticking out behind it in the wall. They promised next day they will be there first thing. They again pitched only at around 12h30, this after I told them 5 days ago I wont be available that day after 12h00. They again said next day first thing, never pitched. Now they dont answer my calls and if I phone another number Caro answers and after I identify myself she drops the call. They are a small shop run by two youngsters Caro and Shaunn with no good sense of customer service. Never phones you back and never do what they promised. Good luck if you go against my review and decide to use these people.
