I wanna know why there is a $27.95 and a $2.99 pending on Apple/billing

Please see this Apple support article→If you see 'apple.com/bill' on your billing statement - Apple Support

And more generally, here is a one-stop link for billing questions→Subscriptions and Billing - Official Apple Support. You can review your purchase history to see what you were charged for, cancel subscriptions and request refunds.
