We have implemented a blacklist on SAInPay division for the following 3 BINS, for refunds only



These BINS cause format errors due SMS transactions being sent to Nedbank as DMS transaction. 


What do we see?

The transaction returns a "successful" result, however the transaction does not reach the issuer/card. 


How do merchants then refund there cards/BINS?

A manual refund needs to be processed by the merchant e.g .EFT



What is being done to resolve this?

Nedbank, Tymebank + other and PASA are trying to resolve.
