Commander et payer

Pourquoi mon paiement est-il refusé? Comment changer la devise affichée ? Quelles sont les méthodes de paiement acceptées par BUYDO ? Comment saisir correctement mon adresse de livraison ? I got charged, but there's no order. What should I do? How can I change the size/color/version of a purchased item? How to cancel an order? The contact information I provided was incorrect. What should I do? I can't find my orders Can I delete some of my orders?
