They gave us the wrong heads (We paid $100 extra for upgraded ones)
They TORE UP our yard, leaving us to fix it.
Cut our cable line & Cut our neighbors sprinkler line!!!
Then to top it all off, didn't call us back after dozens of calls and messages to several different people!! Finally after over a week, called and said they wouldn't pay for the damage THEY did, but would give us free winterization! F You!
