Sean from The Heat Pump Specialist installed a brand new aircon for us

Sean from The Heat Pump Specialist installed a brand new aircon for us. His installation was swiftly done, and all was well until we paid over his final amount. After the installation was done, we realized that this brand new aircon isn't working at all. We suspect that it's losing gas and pressure. We immediately notified Sean, and it's been weeks and weeks of empty promises from his side. He still hasn't come to fix it. For weeks, his been promising us that he will come, but every time, it's some sad story from his side as to why he didn't make it again to come and fix it. This is a brand new installation that has never worked. Please stay away from this company! You will lose your money.
