Who’s the receiver?
You’re not the owner of the currency cloud account… Revolut is. And that’s how they send money and keep pooled accounts (I’m sure you’ve read that in FAQ and terms). So, you can’t have such statement.
But, who’s the receiver who ask for this? because there are two options:
They state that the incoming money has to come from the owner’s account (so, no pooled)
You didn’t put any reference for the receiver so they get some money but they don’t know from who… because they get the money from Revolut (pooled accounts), they don’t know who’s in the background of that transaction
@AndreasK maybe you can help him
