Missing proof of purchase

I was looking at skins for the character Fuse in the game Apex Legend. When I clicked on the skin called "Cybernetic Payload", I automatically clicked the left mouse button twice and the "Buy" button was exactly in the same area and the skin was automatically purchased without confirmation of purchase. I ask you to cancel the purchase and return the in-game currency, as well as make protection against such purchases. I am very upset about what happened.
