I face a similar issue, sent money 2 weeks ago from Revolut to a Czech bank and they weren’t received at the destination.
I asked the recipient to check with his bank and he confirmed that the money didn’t arrive, the bank can’t see any transaction coming from Revolut to that account.
IBAN was used to send the transfer.
Please advise as there seems to be no way of tracing or reverting the transfer.
Thank you!
