I'm not surprised. I've posted before about robocalls that feign being a real person. When you ask "Are you a bot?" they actually answer they are using a computer to improve their messaging.
The call starts the same every time. "Ginger?" when you answer the bot responds with something like, "I'm so glad I've reached you." Then the sales pitch starts. Next time they call, I'm ready. I'm going to answer,"Mary, it's been so long, I can't believe it's you," to see what hilarity ensues.
A couple days ago I tried "chat" to resolve a Comcast problem with my email. I know from past experience the 'person' you are chatting with is a bot. At the end of the unresolved problem the bot started a sales promotion, complete with all the same tactics some spam call sales people use to keep stringing the caller along. I ended the chat but I can imagine someone convinced there was a real person on the other end might have the same ingrained social response to be polite as they would to a real person and not just hang up.
I have never been so socially correct myself. I hang up on these guys who use the string-the-caller-along tactics all the time.
