The purchasing process in F1® Mobile Racing is designed to prevent accidental purchases, with the inclusion of multiple confirmation steps and notifications before your Coins are spent.
Because F1® Mobile Racing is a live, online multiplayer game, reversing changes would have adverse effects on other players you've interacted with. As we can’t turn back anyone's in-game progress, or remove features, providing this refund would put you in a privileged position, which we see as unfair to other players who earned the same item or upgrade through their own Coins or gameplay.
