<prompt> Human: So Im paying for my university accomodation via a MasterCard and I sent some pdfs with credit card info to a random Dude that shares a similar email to my cousin who I was emailing the forms so he could fax them.I put down my name, credit card number and expiry date and a phone number not the security number. What the fuuuck should I do? Ignore and let it slide? Is this information enough for a scam?  <response>: Why take a chance? Call your credit card company and report the card lost. They will deactivate the number and issue you a new card.
