Keep calling with this number. When I don't answer, they call back within minutes showing only "0" as call originator number. When I Google search this number , no information available.

I answered and played around with them for a bit. They old "I'm calling from Microsoft" story. Scam 100%

I'm getting constant calls from this number claiming my computer has been hacked or it has a virus. Once I told the caller, "Sam," he needs to get a real job and stop scamming people and he started swearing at me. I laughed and hung up on him.
