Which I found amusing at first, especially since I run a Mac ;)
The first time they called, I hung up immediately since I had better things to do. The second time, though, I got fairly annoyed at the guy who sounded like he was on the other side of the world in a shack somewhere. I wanted to probe him and ask questions - he claimed to be calling on behalf of my ISP, but did not disclose a name. He wouldn't answer any of my queries and kept on talking and talking - until silence and hung up.
And here I was planning on setting up a Virtual Machine and let them tinker with it to see what they did if they ever called me again - guess that ain't going to happen any more!
