Tell her that the cards she has tried to use before have been flagged as stolen. As such, you require a copy of her passport and both sides of the credit card before you can process her order. Tell her it doesn't matter which credit card she uses, you require the same thing for all of them, so she need not bother trying to place new orders until she sends the required documentation.
If she continues to try, then keep declining the orders.
