It is not possible to issue a partial refund on any payment that has been made online. You will only be able to refund the full transaction.
Issuing a partial refund is only possible for payments that have been marked as having been made 'offline'.
Important notice - when refunding an online payment, the system will refund all payments relating to the transaction. So, for example, if Mum, Dad, Max and Megan paid for their separate memberships in one transaction, refunding Dad's payment will refund Mum’s and the kids too as one consolidated amount.
