Just got a call from the phone number 147-548-7455. My husband picked it up and gave it to me because he knew I've been having problems with the computer lately. I've heard about these Microsoft scammers in the past and that's what it sounded like to me, heavy accent, very unprofessional. He said to check my computer because he can help me fix the problem. I told him off and hung up on him. This area code sounds very fishy to me too, don't know if it exists.
