I paid nearly £200 for my boiler to be cleaned but was left without a functioning boiler. I asked multiple times whether their cleaning products were safe to use on my boiler and was assured that they have undertaken boiler cleans plenty of times before. This was not the case. Their cleaning products tripped my electricity and so I was left without a functioning boiler for 2 days. No hot water or heating. In this current health crisis and having vulnerable elderly parents, I was so disappointed to have been further inconvenienced. At my own expense, I then had to call out an electrician who said that they had left the boiler "sopping wet". I called multiple times and was just given the run-around. Not one member of staff apologised, instead my complaint was met with such hostility. I have never experienced such poor customer service in my life. No empathy or understanding for their customers.
