Had an issue with aircon showing an error code, technician came over misdiagnosed and replaced some parts and filled the gas charged me $990.
After a month ago the same error appeared again called the same technician he came over and suggested it's a leaking issue not parts and quoted me for another $900.
So shouldn't have a warranty do I have to go ahead pay again? Is there a ombudsman for this in Queensland?
What did the AC dude say when you challenged him?
