Call from this number 5 times today (so far!), and 3 times yesterday. No message. Shows as "name unavailable." In my prior experience, name unavailable was almost always the microsoft scam.
This number has called me at least eight times in the last two days. No Message left. I called this number and the recording states it is not a valid number.
No kidding? Look at that fourth digit to see why as 0 and 1 are not used to begin prefixes or area codes in N. America. You can bet it's an overseas call and one you'll want to avoid entirely. No messages left, either? Of course not, why and what is there for most scammers to gain by leaving you any unless it's a bogus IRS call where they'll threaten you? They do know your number works with the culprit being the chance they get to leave you messages. Unless you leave your personal and financial information, along with instructions to break into your computer on your outgoing message, they need a live voice. Want the calls stopped, allow unknown callers NOTHING when they call and be patient.
