Once you have
realized that you selected the wrong payment gateway, you can click on
the Back button and return to the payment selection page, provided that
you have not already clicked on ‘Confirm Order’.
If you have already clicked on confirm order. Contact our live chat to ensure that the payment has not been charged. Once you have verified that no payment has been made, you would have to place a new order as we cannot change the payment selection once an order is placed.
