The engineer who attended was not interested in finding the source of the leak, or to minimise the damage. It was me who had to manually shut off the heating exchange unit where we saw some water near by. It was obvious that the source of the leak was somewhere very near. He was actually putting his hand on the source and did nothing. Two days later when I had another engineer to have a look he saw that the joint just behind the unit, which your engineer was touching, has dislocated. All the engineer wanted was to call for another team to pull the ceiling down and investigate the piping from the boiler to the unit, while the problem was a very simple one. So, I am very very disappointed by the attitude and honesty displayed. They are not interested in solving people's problems, only to maximise their workload and income.
