There are a number of reasons why your Credit/Debit card may have been declined. You may have gone over your daily transaction limit or exceeded the card’s available credit/debit amount. Alternatively, you may have entered an incorrect digit for the card number, expiry date or CVV code. For this reason, please verify that these are correct. Also make sure that your card is valid and has not expired. Finally, check with your issuer to make sure that your card has been authorized for online transactions and that there are no protections in place that are preventing us from charging it.
