I received an email statement saying purchased an app called subscription of magic pain by smule I didn’t purchase this. Is this a scam? How do I make sure I’m not charged for it ?

Identifying legitimate emails from the iTunes Store - http://support.apple.com/HT201679 - lacking in specifics, the next link is better:

Apple e-mails address you by your real name.

Apple e-mails originate from @apple.com or @itunes.com

Mouse over links to see if they direct to real Apple web sites.

View, change, or cancel your subscriptions - https://support.apple.com/HT202039 - "Your membership or subscription might renew if you don't cancel your membership or subscription more than 24 hours before your renewal date." At this stage the renewal is considered a purchase. For a new subscription the sale is probably effective from when you first agree to subscribe. Deleting an app does not cancel the subscription if it has one.

If you see ‘itunes.com/bill‘ or an unfamiliar charge on your bank, credit card, or debit statement - https://support.apple.com/HT201382 - "Before you contact Apple to request a refund for a charge you don't recognize..."

1. Probably. If desired, manually check your iTunes Store purchase history.

2. If it shows up in the purchase history, change your password, click here, and contact the iTunes Store staff.
