Unable to Release Authorizations in Stayntouch PMS Due to "Payment Gateway: Error with MLI. Misc:57 - SERV NOT ALLOWED"
REASON FOR THE ERROR
A 57 decline code is a general "Service Not Allowed" decline response. This is a common decline message for transactions that are blocked by the bank that issued the card.
The error message is also recorded in the reservation activity log:
There are two options for resolving this error (described below).
Option 1
You can use a workaround to release the authorization via the Property Management System (PMS) by charging a small amount to the credit card in the bill that has the credit card authorization followed by a refund of the same amount.
By charging 1.00 in the guest bill that has the authorization, you trigger release of the unused authorization. Then, refund the 1.00 to the same card in the same guest bill as in the example below:
Example of a payment and refund in the same guest bill:
Option 2
The customer (your guest) must call the number on the back of the card and ask the bank why they are declining the transaction.
