We've just had a new shower - which we purchased - fitted by a plumber we've used before and who we've had no issues with.
The start button doesn't work properly. I have contacted the company for a replacement part.
We have already paid the plumber for the original work. Do we have to pay him again as I am assuming that a) he will need to be paid again as this wasn't his fault and b) the product manufacturers won't pay for fitting costs?
Advice welcome and AIBU to think it's not fair we have to pay for something that's not our fault?
