Caller ID says "Hinsdale MA". They leave no message.
I call back after hours (using *67 to block my number). Their message says, "Thanks for calling. The survey you were called for has now finished. If you would like to be removed from our list for future calls, please, press 9." (I never do this as it can actually make things worse.)
So a spoofed caller ID and the failure to identify themselves on their outgoing message. Smells like a SCAM.
I have received these before. I doubt that it is a survey. I suspect they are phishing for information. Give them none.
Hah! You can't fix stupid! Called 9:00AM on Labor Day holiday. No one I know would call anyone at that hour on a holiday when people have an extra chance to maybe sleep in a little ... (unless there were prearranged plans, etc).
