Dear Customer
Since 21:22 GMT - 5 we are having problems with FISERV in MEXICO and ARGENTINA for PayU platform, declined transactions increased with response codes like PAYMENT_NETWORK_REJECTED, which indicates that we present a transactional degradation, however, the network does not present a total drop. We are working together with our Support Team to get a quick solution.
A SMALL subset of our customers may be experiencing declined transactions, we apologize for any inconvenience this may be causing.
Sincerely, PayU customer service.
