As payment is taken at the time of placing the order, we are unfortunately unable to change your payment method once the order has been placed.
We are however happy to assist in cancelling the order, so that you can place this again with your alternative payment method. Please reach out to our customer care team, by submitting a Support Request.
When sending a Support Request to make changes to your order, please select the option “I need help modifying an address, item, or payment method on an unshipped order” and provide your order number in the form. By contacting us through this form, the processing of your order will be placed on hold which will help to prevent it from being sent before the requested changes are made.
Please note, we may not be able to make the changes requested if your parcel has already been fulfilled or dispatched.
