He was reading a script and his calls are being monitored by the manager.
I try to be polite because they are "working" and not taking $ from the system. I have heard that many of these people have had "issues" that prevent them from getting other jobs. That scares me - so I would never give any credit info. etc.
If you answer the phone & it takes a few seconds before someone comes on the line it's going to be one of those calls Hang up before they get on the line. LOL
