Banks may decline a transaction as a security measure.
Sometimes, banks use security blocks during transactions that they do not recognize or are unusual. This may have been the case with your credit card.
Credit Card payments - Please check directly with your bank why they blocked the transaction and approve the charge.
PayPal payments - Please contact PayPal directly and ensure your PayPal account information is updated.
Active subscribers - To ensure that your subscription can be renewed, please check whether the credit card information on file will still be valid at the time of renewal. You can update your credit card information within your My Account > Options & Payment.
