We recently had some issues in our house. Someone came out and quoted us for some work. They came to do said work but discovered some of it wasn't actually needed so it wasn't done (think digging up, so presumably quite labour intensive and this wasn't actually done in the end). They've still charged us the same amount. We've asked them to reduce the bill as they didn't do all the work quoted for and they're refusing. Do we have a legal leg to stand on? Surely they can't expect us to pay for work they didn't do just because they quoted for it!
