I got a fake german tech support number. There company name is Premium Techie Support. They are running the common scam showing errors in Eventviewer and running the tree cmd and saying you got the koobface trojan. They will answer in (bad) german but all of them speak english too. And they got a english number too.
German number: +4908001830533 (its free to call in skype)
English number: +1800-912-9394 (toll free)
