The best thing to do when your card is declined is to call your issuer and ask for another one. There are many common reasons for declines. It may be an authorisation problem that is easily fixed and resolved later. If you do not have another form of payment to use, you should save your purchases until later or call a friend who is close by. Once you have resolved the issue with your issuer, it is time to call your credit card provider and request a new card.
