This will depend on the status of your order. Please check Order Tracking to find out the status of your order.
If your order is at ‘Order – In Processing’ status, then that means it has not yet been moved onwards to picking and packing. Within your account there is the option to ‘cancel’ your order.
If you cancel your order, then create the order again with the correct details then this will be the quicker option for you.
You cannot directly edit an address yourself on your incorrect order. This is why you need to cancel the incorrect order (if it’s still cancellable) and then place your correct order.
