Metroplex Leak & Line Locators

We had a leak in our home under the slab and needed someone to find it. Did a general internet search and chose Metroplex. Took serviceman a LONG 4 hrs to find out where the leak 'MAY BE'. The total bill was over $600 just for him to tell us that he wasn't sure. He also replaced a valve on our water heater which we were told would take approx 15 minutes. This turned into an hour. Spoke to his supervisor who was not at all concerned w/the misleading info we were given. WILL NEVER USE THIS COMPANY AGAIN. I sent an email explaining how dissatisfied we were w/their service and did not receive a response. Of couse, why would they respond when their worker had already jilted us out of $623. It took him 4 hrs to do what could've been done in less time. Let's not forget that Metroplex would have charged approx $1350 to fix it after getting our $623 to find it. Anndddd we had to pay for him to sit in his van for over 15 minutes just to write the invoice. HORRIBLE SERVICE.
