Had a British gas plumber at my house today and his behaviour towards my wife is highly worrying, unprofessional and threatening. Had to rush myself back from work for safety reasons. After watching the threatening behaviour of the allocated plumber on the video clip on my wife's phone, I had no choice but to launch a complaint to British gas and also considering going further to other relevant departments. unfortunately, he's caused more damage to the bathroom. have to be professional at this point and allow British gas to carry out their internal investigation before I move to the next stage.
