Hot water went off so a plumber came .He ordered the part came back next day and fitted it. 2 days later same problem. Another plumber came ordered part and came the next day to fit it but said their was a big bang so he switched boiler . Now no heating or hot water as boiler switched off. Electrician came on Saturday night but was informed by plumber he did not do what he was supposed to. Second electrician phoned to arrange to get all electrical work checked. He said he would be either Tuesday or Wednesday evening. I get a call from Corgi saying he now cannot come till Monday . We are both over 70 All they say is they are sorry. Diabolical company beware folks
