I get a msg from this number at least once a week. I do no pick up a phone if I don't recognize and will not call back it they don't leave a message. They are consistent in calling though.
They've called twice within a week, silence for 3 seconds, and hung up both times. I called back. The first time it had an automated "leave your message". The second time only beeps and disconnected.
Caller ID shows "Acton MA" for about 3 wks, as often as 3X per day - morning, afternoon, or night. Never answer, Call back and get automated "Leave CLEAR message and number..." with no ID
Calls every week, or two times a week, from this number. Will be reporting it to the FCC via the link below to file Phone Complaint. I'd suggest every other person commenting here does the same.
