Pool Doctor (wynberg) bad service

Pool Doctor (wynberg) came to my property and told me the leak is at a certain point, i doubted their credibility due to the fact that the guy was in and out in about 2 minutes. I got a private company and they found the leak at a totally different place to where pool doctor(wynberg) told me. The leak was fixed no where near to where pool doctor said, pool doctor got paid by my insurance but I dont see why because I paid a private company to sort it out.
