There is an interesting Indian connection....... Dell computers
Dell has a call center in India and the names and phone numbers of all dell owners are known to the employees there. These employees turn over the names and phone numbers of American Dell owners to criminals who using number blocked ID call Americans and scare them with the message that their computer communicated problems.
They then take control of the computer (I think) and create a situation where they get paid.
The callers are very persistent and are immune from being called racially insensitive and sexually abusive names.
I ssk them if they have a refridgerator. And then if it is running....
