I know the feeling I left them after only working with them for a year, I kept finding and repairing installation faults, and they are only interested in money, get in and get out of the house in 20 mins. pressure on visits every day. and 1 customer had an old boiler that they said they couldn't repair as it was to old, so I got the part for her and did in my time. obviously Mum's the word. loads of installation faults they would even fix.
