Hello @soechan,
Welcome to the PayPal Community! I'm sorry to hear a recent transactions isn't going quite as you had expected. Since you're unable to open a dispute on a refund or a fee, it sounds like you may have opened a dispute on the entire transaction. However, normally you wouldn't see an extra on PayPal's side for making an international purchase unless there was a currency conversion involved. With that in mind, I would recommend reaching out to our Customer Support teams to dive a little deeper into the Transaction's Details to see what's going on.
Good luck with this and future transactions!
