Supra builders leak detection rip off

Supra Builders claim to be able to find water leaks. They came to my house and said there was a leak under my driveway. After digging up the driveway no leak to be found. Turns out the leak was some 30 meters away. Even after giving them a 2nd chance to confirm the leak they could not. Despite leaving a number of messages and emails for the owner to call me, nothing. Don't use Supra to find your water leaks they are clearly out to rip you off.
