What's with these people; they keep accusing me of various things and I don't even have an account with them that I know of?

I clarified things about a year ago; now they're trying to say I'm selling Diablo accounts ?????

I wrote them back telling them to stop harrassing me, and I guess I'll have to call them as well as their site has minimal supervision.

How does a big company like Hotmail deal with another big company like Blizzard Entertainment when they just up and decide to start harrassing this individual; how do I get them to stop harrassing me other than just going to the police?
