Charged Without My Notice for 59.99 from Apple??

I got charged for something I didn’t buy. It was for 59.99, there’s no code, and it’s an Apple.com/bill purchase. I can’t update anything anymore and I just changed my password. It’s frustrating. How do I fix it before it starts charging me a third time? The purchase is not pending on my debit card’s account, and it doesn’t show up in the recent purchases on my iPhone.
