It's not just double glazing salesmen who are like that. We had a burglar alarm guy years ago and he wouldn't leave. Prior to him coming we'd actually had a phone call to say that he was approved by the police and advising people on security. When he arrived he had some official looking bumph from the police, but he stayed for hours and wanted us to buy his wretched alarm system. I actually phoned the police to check if they had approved this firm and the worst of it was - they had! But they only thought he would come round and talk about security, not be an aggressive salesman. When we told them how long he had been here and his approach to getting us signed up (accused Peter of not caring if I was raped and murdered in the night.) they said they would not be approving them to visit anywhere else.
