In order to process the payment, please ensure that the address that you are entering under Billing Address is the same as the address that you have registered with your Bank.
In case these addresses don't match, your transaction will be declined and the payment will not go through. Please avoid this by making sure that your Billing address and the address registered in your bank are the same.
Please be mindful that after three failed attempts your card will be blocked for an hour. Please try processing the transaction again after an hour with the correct details.
