What a cock!!! We get it all the time, had a customer who wired his own hot tub (very badly lucky he dint kill his family!) And 12months after we had redone his shondy job properly he phoned to tell us the 1200quid pump on it had failed and it was our fualt!?! Wtf lol my boss told him to fuck off after he produced a "engineers report" which my boss ripped to bits with incorrect facts and info on the pump configurations. Bloke clearley ran the pump dry fooked it then thought he would try and get a new pump out of us!!
