Accidentally purchased wrong battle pass

Bummer, thanks for the quick reply. Was hoping that something like a pre-order where nothing has actually been received yet would be different. 

Totally understandable, @Trapy0ung.

Typically that's possible with pre-orders that have their own transactions and can be found in your order history, but the in-game options work a bit differently in that regard and are essentially final once something is selected and confirmed.
