Notify your bank! Their "Fraud Department" will be able to block further monies being drawn once the $46 is taken, and also block them from their banking system! Once the money is taken your bank will help you with "Grievance Forms" to fill in, and as your payment was taken via card details, they should be able to get your money back! I hope this as helped you because I am going through same thing!
