I know! I can't believe he treated me that way. And what makes it even worse is that I don't feel there's anything I could have done to make him pay for the repairs himself. According to the CAB I would have had to give him the chance to repair it himself first, which he clearly wasn't going to admit even needed doing. And then, to take him to court to get someone else to repair it, would cost ridiculous amounts of money and would end up my word against his...and I'd be more likely to win the lottery than win the case.
Ah well, at least I didn't pay his call-out fee on the day he broke it (and oddly enough, he hasn't been chasing it up either).
