Communication breakdowns.

Due to some communication breakdowns, a bedroom aircon was replaced, and it didnt need replacing. The aircon replaced should of been the 'gecko' damaged one, in the loungeroom not the aircon in the bedroom which we were going to repair/replace under warranty. Recently the other broken aircon in our loungeroom, was to be replaced by a new 'Mitsubishi Heavy Industries'. I emailed our property manager at that time, requesting a new,'Mitsubishi Heavy industries', due to finding the existing aircon brands unreliable. Then after installation I looked at the 'PropertyMe' photos online and was dissapointed to see, it wasnt the one we asked for. It was the wrong brand of air con installed, not the one we asked for. I have found simple requests like, a few before and after photos when a tradesmen is doing a repair or maintenance, has been poor. Roof & gutter maintenance was another issue. Approx 3 - 5 months ago, my neighbour in crestmead informed me that a huge weed had been growing out of the roof gutter at the back of my property for over 6 months, despite a gutter cleaning service I paid for approx 2 months before. I noticed this was also missed by a routine inspection. Things like this, not getting picked up worries me. Either the tradesman didnt follow simple instructions, like 'before and after photos', and 'cleaning all the gutter's', or the requested instructions were not passed on. The reason's we like to see a few before and after photos is because we are interstate, job quality, and if the actual work has been done or completed. More roof & gutter photos would also allow me to work out the best frequency of gutter cleaning, due to many overhanging tree's onto the rear of my property. To prevent future problems more frequent phone calls, might work, though mostly using emails when it comes to maintenance. Regards John & Catherine
