My friend got a boat mechanic off the internet who comes to his house to work on his boat. The guy takes the drive off and brings it home does some repairs and comes back. The hourly price is agreed on and the drive is replaced however now the repair is not done right it is a simple water pump replacement, replacement for matainance reasons only. The mechanic takes the drive off and says he will bring it home and fix it and bring it back. He takes it and leaves now he calls back and wants a lot more money to bring it back and wants to be paid before the job is complete and is holding the drive hostage unless he is paid the money first. My friend is stuck and does not know what to do is there anyone who regulates these guys or someone to complain to.
