No — once an order has been placed, you can't change the payment method for that order.
Why you can't change payment methods after ordering
Payments are captured at the time of ordering to confirm and process your order. We can't switch the payment method after the order has been placed.
Update your payment method for future orders
You can update your payment method in your Huel account for future orders:
Log into your Huel Account
Go to Payment Methods and add your new card details
If you have a subscription, link the new payment method under My Subscriptions > Manage Subscription
If your order payment fails
If your order fails due to a payment issue, you'll be able to update your payment method before reprocessing the order.
