No — once an order has been placed, you can't change the payment method for that order.
Why not?
Payments are captured at the time of ordering to confirm and process your order
We can't switch the payment method after payment has been processed
What you can do
For future orders:
Log into your Huel account at huel.com/login
Go to Payment Methods and add your new payment details
If it's a subscription, link the new payment method under My Subscriptions > Manage Subscription
Tip
If your order fails due to a payment issue, you'll be able to update your payment method before reprocessing.
