Lawn Plumber Irrigation

Trying to find an irrigation repair service. We did have lawn plumber come out to do the turn on service for the season. We used LP for the first time as our previous person did retire. LP came out and also put flags out as we were having some trees planted and wanted to try to avoid the irrigation system. He did state he did not guarantee the work, but, after the first tree did hit the irrigation system.....I have sent text messages and inquired for LP to come back out to give an estimate on the repair work and he has not returned my calls.
