Why is they trying to make me pay for instagram when the app is Free

Apple charged me a total of $7.33 monthly from March to today for Instagram Subscription 195. Because I had other purchases from Apple I never checked my receipts until today as i didn't know why i got one. Anyone know why Apple is charging for the Instagram App? Also Apple is not permitted a refund you can only cancel the subscription.

They aren't making you pay for it but you do need a valid payment method on file with Apple to be able to download apps, even free ones. It's for identity purposes and also for in-app purchases.

If they need you to put in your apple id password that doesn’t mean they’re gonna make you pay check if it’s says the price if it doesn’t it’s free (i think)
