First, if the deposit was pre-authorized, that is, it occupied the card limit, but there is no need to repay it temporarily, and no details can be found, then the settlement will be made with pre-authorization, and the actual amount paid will be deducted from the pre-authorization, and the remaining part will not occupy the card limit.

Second, if the pre-authorization is made by credit card, but the payment is finally made by other means, then the amount of pre-authorization will be restored.

Third, at that time, the payment was made directly by credit card, and the details could be found when the transaction was recorded. The cardholder's repayment method is not pre-authorized, so if there is a refund, it depends on the refund method chosen by the hospital, whether it is cash refund or credit card return.
