You should be able to dispute the charges. If it was your debit card, there is a time limit for you to dispute the charges, so you should do so as soon as possible. Your bank has the forms. The form will ask for the amount and whether the card was in your posession at the time, if you've ever given anyone your pin number, and such. The bank has a fraud team that will investigate the charges and how they were processed. Unless they can prove that the signature matches yours, or that your pin number was used, you will get your money back without the need of an attorney. First things, first; go to your bank and dispute the charges. Let us know how it works out!
