Called just now at 6:39 am. NO ONE calls me that early unless it is an emergency, so scared me. Said he was "from Microsoft", I told him it was very early and he needed to remove my number from his call list. He hung up.
Received call from this number at 5:50 est. Caller ID came up as "unknown". No message left. I called number back and after one ring a recorded message played telling me that the number is in service and to try my call again later.
Caller, speaking with a very heavy accent (possibly from one of the Indian subcontinent countries), claimed to be calling from Microsoft. Since this is a very well known scam, I replied, "No, you're not!" and hung up.
Phone number is most likely spoofed.
Call type should read, "Likely scam," not "Unknown," but it was not an option.
