For technical reasons an reversal advice can be declined if PayEx is unable to store the transaction. In this case the third party host need to retry the advice until manual intervention or the advice has been accepted. It’s expected that the third party implement a retry delay with exponential wait time between retries. After 6 retry attempts have failed manual intervention by third party and PayEx support must be initiated.
