A local plumber was recommended by my friend. I wanted him to sort out a leak under the bath. He made 2 holes under the bath and 1 in the ceiling to find the leak. The leak was found after he made the 2nd hole under the bath. I asked him about repairing the hole in the ceiling and he said he didnt have any materials with him and would be in touch. I received an invoice requesting payment for 2 visits to my home but he hasn't fixed the leak or the hole in the ceiling. Any suggestions on the best way to proceed? He didn't give me any documents such as a contract before starting the work.
