Very disappointed.For years I used this company. Today they sent me two guys unannounced. I sent them a way. The worker said this is their new thing: they send the guys, they do the work then GSG charges even if the customer never ordered the service. I called and spoke to Chris who seems to have become a used car salesman overnight. | The worker told me all week he has had people turn him away since they never ordered the service. I am disgusted with this organization.
