There is a dropdown in which all IBAN numbers are listed from which you have deposited. Sure, they could now try to block Wise there. But in the end it’s a never-ending story, because there are probably dozens of such services like Wise. And then there’s Revolut, where some have their own IBAN and some don’t depending on the country (possibly also the case with Wise?).
What I agree with you:
- According to your description, it takes too long to solve the problem. That’s not good.
- Saxo could put an info under the dropdown that the account should be in your own name.
