I walked off a job today where I had quoted £65.00 plus price of part to fit a new pcb to a 24 cdi. I had been given the wrong price for the part by the suppliers and when I went to pick it up I was charged thirty quid more than I had told the customer. I got the pcb anyway and took it back to the house and explained to customer and even gave her the reciept. She told me to fit it anyway but when I went upstairs to fit it I could hear her on the phone complaining to somebody about my labour charge. It went something like " 65 pounds I mean why 65, why not 60 what's the extra fiver for" in a very agitated voice. Now I was listening to this having just spent 163 quid on a pcb which, if I fitted would be non returnable, and I got a funny feeling that if there were any further problems with this boiler I would have trouble getting paid. I originally went out sat evening and the boiler would not run, it was sending an on/off pulse of power to the pump and fan about every second continually. To my mind it could only be the pcb and worcester tech line confirmed this. Anyway when I got that feeling I just picked up my tools and parts and walked out, she wasn't very happy when I told her to get somebody else. Personally I thought 65 quid for 2 visits and a trip for the part was too cheap anyway.
