Grasshopper Lawn Service

After 2 years of treatment we are loaded with crabgrass. I called and spoke with a supervisor who stated it wasn't crabgrass, never sent anyone out to look. When tech arrived 3 days later I said I was unhappy with the service to which he replied that he doesn't have a vested interest in the company so he didn't care one way or another if we went with a different company. Also said a company the size of Grasshopper is not at my beck and call. Totally disrespectful. Would not recommend. They are expensive with poor results
