can anyone advise please, i called out a plumber because i was having trouble with my boiler, noise, cutting out, locking, etc. he took a look and sid there isnt much wrong and that it needed re charging, he arranged to call back the following week and charged £45? this was over 6 weeks ago , and when i phone he says he is to busy working on a housing project. he is the only plumber for miles and no one else will come out. can anyone give me any tips for the sake of my two shivering kids.thanks
