Who called from 4252963141

Unsolicited call from "Joe" of a "health and safety" company, wanting to sell mobility and other services to seniors.

Kumar from Micro-Soft Emergency Anti-Hacking Team again, letting me know that a hacker was trying to take over my computer (again), but I think he already broke in, because all I get is a red and black screen about files encrypted with military strength and to send bit coins to someone.
