Had some work done on my chimney a while ago to stop it leaking. Work was done, paid for, all good. Except, when we had heavy rain, chimney still leaked just as bad as before. Asked roofer to come back and fix it. After nearly a year, he came back, had a look and said it need more work, he's another quote to do it. I asked if he could at least deduct the money we had already paid. He said 'no' because that was to pay for the first bit of work. I said that I want my money back then, he said 'no' to that as well.
Anyway, it's clear he isn't going to fix the work without me paying £££ more and he's not going to refund me. I sent him a message to say I am going to take him to small claims court. He replied 'how dare you threaten me' and that he's going to come round and remove the work he's done if I do.
What would you do?
