If you really wan to get your revenge, use small court claim in her city. collect all information. Notarize them, ask your friends or relatives to submit the case for you. But do not know how far it is, you still need to be present personally
You can also file a internet crime complaint here

Do not know how much it will help, but my case through ebay was resolved by an FBI agent.
