Caller ID says "Cell Phone MA". They leave no message.
I call back after hours (using *67 to block my number). I hear the following, "The person you have called is unavailable right now. Please, try again later. <again in spanish> Message 2 switch 1 5 7." This repeats. Then I hear the following twice, "We're sorry your call can not be completed at this time. Please, hang up and try your call again later. Thank you"
So they spoof their caller ID; they leave no message; they can't be called back. Smells like a SCAM!
