Regarding reversal processing: We have confirmation that Mastercard reversals have been processed successfully. Visa reversals are ready for tonight’s processing cycle since no option turned out feasible for inclusion in an extended cycle. Visa will circulate an announcement to issuers when the reversals are successfully received by Visa. We will update this incident as soon as the announcement is circulated; expectedly today. Expect the next update no later than 2021-10-13 12:00 UTC.

Update
We have confirmation that we are able to reverse the duplicate transactions. For a pair of double transactions, the first transaction will stay whereas the second will be reversed; and it will be reversed with the posting date being the same as the second transaction. This ensures that cardholders should experience no consequences as for currency exchange rate fluctuations between the day of the second transaction and the reversal.

We are doing our best to have the reversals executed with schemes during Monday’s clearing cycle, i.e. the night between Monday and Tuesday. This incident will receive an update on this no later than Monday afternoon, 2021-10-11 15:00 UTC.

It is important to note that since we will automatically process all reversals (both purchase transactions, refund transactions and credit transactions), please do not manually reimburse cardholders or alike. We have reached out to schemes to get the information to issuers to hold back potential chargebacks that could otherwise be created due to this incident. This incident will receive an update on this no later than Monday morning, 2021-10-11 09:00 UTC.
