I keep the service however, I am very unhappy. I called last year because my entire yard was taken over by weeds. I called and asked a manager to come see. They sent a guy out who said he was putting out fires. He said they were mixing the weed killer with the fertilizer so it was killing my grass and growing weeds. He said give them time they will correct it. I gave them time it started looking better. Now the weeds are taking over again . I don't understand if I am paying a company to kill the weeds and fertilize my grass, why is my grass dying. My yard looks terrible. What is the problem?
