Immersion heater was broken so rang up in the morning to get it sorted as no hot water. Was told that they would arrive by 2. Didn't arrive - everntually turned up past 5pm. Plumber told us he wasn't told it was immersion heater problem so didn't have the parts. However said they would get out first thing tomorrow to fix around 9am latest 11. Waiting the next day no-one arrives ring up to be told that no-one will be with us that afternoon. We were booked with friends to go out so couldn't. As a Saturday no available appointments till Monday. So left w/o hot water for three days, when could have rung someone else and got it sorted on the Friday.
