These clowns had some nice looking women up at Sam's Club in Gaithersburg one day a year or two ago, and I signed up to get a quote for windows. I confirmed the appointment the night before, but when they called to tell me the quote guy was running late, I told them my son had pink eye or conjunctivitis, and that I wanted them to reschedule. They acted like I was lying because I didn't want to keep the appointment. I told them to come on by, that I didn't care if they came out or not. They never showed, and didn't call back for a month or two. When I told them that they failed to show, failed to call, and that I had purchased windows elsewhere, they were to remove my name from their list. Today (more than a year later) they called again. I didn't answer.
I just said the person they were looking for (yes, me) was not there. No one with that name. They said thanks. Then I added their number to by blocked list. Problem solved.
