Your service has been treating my lawn for some time. This summer a brown patch grew in the front yard. Your regular service failed to service it. I called for help and was told a manager would call and make an apointment to come out. I waited a week and called again. A supervisor came out and ordered another treatment of the area. I was billed for this. Why??? It should have been taken care of sooner with the regular applications. Not righht!!!!!!!!!!!!!!!!!!!
