I accidentally bought a skin and I want a refund

I was inspecting Caustic skins just for passing time, waiting for my friends to get in the game, then accidentally bought a skin costing 1800 AC which I did it by mistake and a misclick. The point is, I don't even play with Caustic anymore and plus, I really don't like that skin at all. I wanted to buy a skin from new SF6 event with my AC and it's all now gone. I'd like to ask, would you kindly help me in refunding my Apex Coins and I spend them again on the content I love to use in game?
