Je viens de recevoir de la part de dvdboxoffice :

I would like to take this opportunity to thank you for placing your order with DVDBoxOffice.com.

In order to process your order as placed, we need your assistance so that we can verify that the credit card information you have provided is yours.

To accomplish this task we need you to provide us with a copy of the payment stub that comes with your credit card statement each month. This stub contains your billing address which you have already provided us online along with your credit card number which you have also provided us. We do not require any further statement information.

Please send this information to us by fax at: 905.709.4073 and be sure to include your name and order number so that one of our representatives can email you back to confirm receipt of your paperwork.

On est obligé de le faire ou c'est facultative ?
Sachant que ma commande est en pre-order.

Merci de votre aide.
