Hey Msamavat! I’d recommend contacting our customer service once more as they can help you with this issue! 

I had a similar issue with a Revolut bank account where an NS direct debit failed.

Trying to change the IBAN gave me an error, so I had to contact NS Customer Service. A few weeks later, I changed the IBAN back to Revolut and since then all is fine.
