I got charged 4 dollars when downloading this app

Google drive is supposed to be free and it was on icloud I got charged 4 dollars and I can’t even get a refund because it doesn’t say on my purchase history that I bought anything, it even did this when I downloaded Google Earth, I am not happy because it said I bought something but I didn’t it charged me 4 dollars for a free app.
