sb used my email address to create an account

I got an email on saturday from teamviewer that i should activate my account by clicking the following link. I did not create this account. sb used an old email address that i used to use for my actual teamviewer acc (but i switched to another email months ago). And the email i got was written in chinese. So i was curious about it. i did not click onto the link. i checked the situation and i came along with the idea to say to teamviewer that i forgot my password. So another email was sent to me to change my password. i changed it and logged into this acc. i saw a directory in this acc written in chinese that says computer games. And there was one computer already signed to this directory. The computer was online so i figured out how to get his ip address. can sb from teamviewer contact me?! i want you to investigate this situation
