I suggest that you film and list the problems. Then get estimates to repair/replace the work to make it the way that it should have been for the work that you have already paid for.
You will need receipts for the money that you have already paid. That should be your basic claim. Add on any other incidental costs - such as having somebody to investigate what was the problem.
Send the first plumber that letter as a claim, saying that legal action will commence on a stated date, unless the amount is paid in full by that date.
Then start a small claims court action for that amount, plus any other costs, eg your time to present the case, etc.
The 'consumer rights' tab from the home page of this site, will provide more information for you.
Good luck. |
