As far as I know, the ticket system is the only place where you can get this situation investigated and possibly a return of what was stolen.
I advise you to do the security quiz (which you can find in the login page after successfully logged in) in the near future and avoid allowing access from third parties through TeamViewer or any other program of this kind to your computer. If you need help with anything related to xat, go to the chat Help or if it's not related to xat, search on Google.
