Report
They were contracted to do trimming for SMUD. They showed up unannounced after being asked to give us notice to secure the dogs, move the RV and boat. The crew leader treated me like I was stupid and bothersome by asking for simple consideration. When they performed the trimming very poorly by the way I asked them to let me know when they were done so i could put the dogs out. They left did not tell me left the 10 gate wide open. We later discovered they broke two windows. They did nothing to fix the windows completely blew us off.
