Can my order still be approved?

It might be that Revolut is not accepted by Simyo, becaus AFAIK they do not provide bank nummers starting with NL

if that is indeed the reaason for cancelation, she should use a real Dutch bank account.

But there can be another reason too.

It would appear so, because some months ago I had the same issue but a friendly support member helped me over chat. But since chat support is gone, I tried whatsapp support which did not go well. So it's not a dead end situation, we just need help from a Simyo support member / moderator. 

Hi @lb5,

Thank you for your message. Good thing you contacted us about this! 

I would have to check with you on your connection, we might need some documents to approve the order. Can you send me a private message with your personal data? I will look up the order in our system then.

Thank you for your reply! @wimj12 😊

Greetings,
