I think you may find that the swindler may be able to present the old CC number and still charge your account (which hasn't changed). Gym indenture companies are notorious for this. I had this occur with Capital One and a scam fax-to-email company who refused to accept a trial cancellation. Even after lodging a dispute the scammers could still bill more charges, and I'd have to dispute each one until the bank made a ruling.
