hi cazzatwin1,
I am sorry to hear that you were scammed but unfortunately it is virtually impossible to get your money back.Your money was taken by a criminal so there is no 'refund'.
Everything about the scammer is untraceable.
His names(Martin Peterson,Tracy,Gabriel Brahe,Nicole McDougal,Thomas Kent)
His emails are from a free email service (yahoo,ssl-mail.com)
His phone number is a mobile,very probably a noncontract/pay as you go.

If you can tell me what country you are in,I might be able to find the best contact to file a report,
