You will be given the option to issue a refund when cancelling a follow-up session, or when marking a session as 'not attended' in the attendance update that appears after each session.
You can also use the Edit Date/Time option to rearrange the session and carry the payment across to a new date. Refunds can take up to 5-10 days to be received depending on the client's bank, so we do always recommend this option if the client will be attending on a different date.
If the session has already been cancelled or marked as not attended, and the Refund Session button is no longer showing on the session details page, please contact the team so we can issue the refund for you, noting the client's name and the date/time of the session to be refunded.
We have instructions here on how to cancel an initial session.
