I have tried on numerous occasions, all of which keep getting rejected.Unfortunately your External Card Transfer to [name] in the amount of [amount] has been rejected.
I bank with Monzo and when my bank reject the incoming payment (from Paxum) I receive a notification stating it was declined. However, on the occasion where the attempts are been rejected my bank is not giving me any notification, which indicates that it's a Paxum issue.
I have opened a ticket with Paxum for some information.
