Caller ID says "East Weymout". They leave no message.
I call back after business hours (using *67 to block my number). Their outgoing message appears to be a pretty good computer generated male voice. I hear, "Hello. None of our representatives are available right now. If you received a call from this number, we should contact you within the next day. If you believe you received this call by error, please, press 1 to be added to our Do-Not-Call list." (I never do this as it can actually make things worse) Note the failure to identify themselves. A computer generated voice makes me doubt their skill with English.
So they spoof their caller ID, and fail to identify themselves. Smells like a SCAM.
