Why has my credit-card payment not been authorised and/or declined?
Credit-card payments do not always go through the first time. If it happens, please ensure that:
Remember that if authorisation does not go through, you will not be charged. If none of the above helps to resolve the issue, you could try using another card or changing the payment method. Alternatively, get in touch directly with the credit/debit card issuer and ask them for support.
