Transfer from Revolut to overseas account

I’m on a working visa in the UK but currently holidaying throughout Europe. I also have a travel card from my home country.

I transferred some funds (in GBP) to my other travel card and only realised that one digit had been entered wrong for the account number when no money was received in the expected arrival date.

It’s been 1 week since the original transaction. What do I do next and am I going to be able to get my money back?

The money should bounce back. Give it some time. I would also inform support that you are expecting the money coming back. I doubt that changes anything, but it might speed up the process.
