Refund time when paid in Battlenet Balance

Hey there, I was trying to gift a friend diablo 4 deluxe edition. I accidently bought the game for myself. I heard the refund time can be long sometimes, however I’m wondering if I refund something paid for with Battlenet balance, will it be faster because it doesn’t have to go through banks ect? I just don’t want to be out $100 for multiple days.

Sorry if this has been covered, but in all the articles I read on refund time, they don’t say anything about battlenet balance payment methods.
