Caller ID says "Taunton MA". They leave no message".
I call back after hours (using *67 to block my number). I hear "<30 seconds of silence> We're sorry your call can not be completed at this time. Please, hang up and try your call again later. Thank You." It repeats and then it hangs up.
So they spoof their caller ID and don't seem to be able to be called back. Smells like a SCAM.
