Great Price but ZERO Customer Service

We recently purchased an Aircon with installation from AC direct and although they are probably the best priced, their service is nothing but appalling. There is literally no human communication other than when you are required to make a payment, they don't update you on the process and the installers simply do not arrive at the scheduled date and time. The first time we moved everything around to be at home and they never showed, when I phoned, I was told the car broke down and it had to be rescheduled. Then we had an issue with a water leak and once again sat around waiting all day for the installer to come and check and once again, we were told the car broke down. It had to be rescheduled and the guy showed up but 2 hours later than scheduled. So for Service I would actually have to give them a big fat ZERO for effort.
