There are a number of reasons for 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. Alternatively, you may have entered an incorrect digit for the card number, expiry date or CVV code, 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 authorised for online transactions and that there are not any protections in place that are preventing us from charging it.
