I have had homecare for years. British gas are trying everything to sell me a new boiler and a powerflush rather than fix the issue. Apparently they don't replace heat exchangers on their contract but there is nothing to this effect in the contract I have with them. There is an exclusion about sludge/limescale if they have previously told you about the issue - in my case they hadn't (boiler serviced for years with them) but they are still leaving us without hot water I am devastated I have wasted so much money and time with this company. They don't care if you have no hot water or heating, they don't want to do their duty Also an engineer (John Oxley) was incredibly condescending to me (a woman), but not my flatmate (a man). He continuously talked over me, told me to listen whilst I was talking and used his mask as an excuse for his rudeness. Also he has done nothing at our visit which we have waiter 5 days for - he has not taken the heat exchanger off, not cleaned it and he left us without hot water. Instead I got a call to get a new boiler in from the installation team - I did not ask for that!! I am so upset, tired - and have no hot water
