Signed the contract, paid a deposit, they sent out a guy to work on the sprinklers, but he doesn't understand English. I spend 15 minutes trying to explain what I want done, which he doesn't understand and I'm paying $75/hour for this? You have to be kidding me! I call the office, they're sending out a foreman, but I'll probably be charged for the time the guy is sitting around not knowing what to do.
