Booked them to install a hot water boiler and was told the job would take about 9 hours. About 3 hours in, the installer left saying that an electrician would call at some point to install the timer. No one called.
The company rang me the following week chasing payment and claiming the job was complete. When they eventually admitted the job was not done, they booked an electrician to come and finish it.
He turned up over 3 hours late and claimed it was sorted. There was no hot water. I rang the company and said another engineer would ring and conduct an over the phone fault finding. They would then ring me back to check all was ok.
The engineer called and, after a few unsuccessful minutes trying to get to grips with the system, claimed that he would go and have a look at the instructions for the system (!) and ring back.
Neither did he ring back nor the company returned my calls or emails
