Depositing euros to Bitstamp via Revolut problem

[satrapus]

I tried to transfer euros from my Revolut account to Bitstamp but got "merchant not supported" error.
Revolut apparently don't allow transfers to crypto exchanges.
They I found out I could create a personal euro account on with its own iban bic code and that I would be able to
deposit to Bitstamp from it.
I now don't know how to transfer euros from my main Revolut account into newly created euro account.
I added a new beneficiary and tried to make payment to it but get "bank transfer failed" error.
Any ideas?
Thanks
