Hello,
Just got a call from this number. They claimed they are from Microsoft Security Department and they said that my computer firewall was corrupted. Also, they said that that I had paid them in the amount of $399 for computer security. I called the number back a few times to make sure it was not a one and done. Flood their call center and take these bastards down.
