I also have a strange expereince just days ago, when financial dept of government (provincial) called me about a company under my name. I never registered any company before and thought that maybe a guy with the same name did that. But then how did they use my phone number.
I suspect someone out there are stealing other's identities to do this kind of things. For example, he can register a company using other's name for tax purpose. I don't know if anyone has similar expereince. The world is becoming dangerous. So be careful.
