no receipts for payments

I've been looking at around 4 apple "purchases" for $6.57 and one for $2.13 on my bankcard but I didn't buy anything. I only have the 0.99 icloud storage payments (that I receive the receipts for). I need the receipts to see what this is also they don't show up for purchase history or subscriptions. do I have to dispute the payments from my bank account?
