Phone BG on Tuesday to come and fix the boiler, keeps going to "lock out". When I told the plonker that it keeps going to lock out he said " .what does that mean is it in a garage and you are having trouble locking". I controlled myself well and explained what lock was, he arranged for an engineer to come today. Engineer arrived and said I have come to repair your slate and lead flashing, this of course meant that he did not have the spares on board to cure the lock out. He was very embarrassed. Again I controlled myself quite well, there was no swearing. I am trying to find a customer complaint number, no luck yet.
