Can't refund battle pass bundle (Modern Warfare 2, Season 2)

Hello, I purchased Modern Warfare 2 back on November 11th, 2022. After season 2 was released, I attempted to buy the battle pass with the 50 tier skips and 4 operator skins for 30.00 dollars, but but it charged me 100 dollars for the full game again and 30 dollars for the battle pass bundle.

Since it's a bundle, I can't ask for a refund, but there has to be a way to get one considering it said the bundle was only 30 dollars and I have had the game for almost 3 months now. If there is anything we can do, please let me know.

:)
