If you are using our payment preauthorization functionality your customer could experience a temporary double charge in their account.
This can happen because the system has not released/deleted the hold on payment but has released the funds to you if you have successfully charged the customer.
The duplicate charge is not an actual charge to their account. It is a temporary hold on payment that will discarded by the bank within 7 business days.
