My mother got one of those calls last year while I was luckily at home. They told me security had been compromised and I had to download some software. But no worries, the software is free! Thank Shiva!
You may be onto something. The address Jamaal gave is a cute little hipster restaurant in Charlotte called 300 East. Just in case, I let them know what is being done in their name and they said they are on it.
