While going through our home warranty, we had fosters come out to diagnose our pool problem. The repair guy never came in the time they said he would, after 4 messages, which were never returned, we gave up. The next day we get a call that the guy diagnosed it as a clog. The guy absolutely never came out, my dog would have let me know, and he said it was a much different problem than what it ended up being after we had someone else fix it. He wasted a lot of our time and it took a lot longer to find someone else to come fix it. Also, because of his bogus diagnosis, we are having trouble getting the home warranty to cover what the actual problem and repair was. So upset with fosters, would never recommend them. Never had them return any of our messages either. If I could, I would give ZERO stars!! Use someone else.
