Caller ID says "MASSACHUSETTES" (extra e is their's not mine). They leave no message.
I call after hours (using *67 to block my number). The phone "message" on their answering machine is just about 2 minutes of silence. Then it hangs up on you.
So we have a spoofed caller ID and the inability to be called back. Smells like a SCAM to me.
I have been getting a lot of these calls lately. All have a caller ID of MASSACHUSETTS with or without misspellings. All unreachable with a call back. Mostly from 508 but a couple from 781 area code.
