Why have I been charged £0.79 in the last two months?

If you're sure that charge comes from Apple (check your bank statement very carefully), start reading this support page:--> Subscriptions and Billing – Official Apple Support, and check each of the first 3-4 sections.

If you cannot find the information you were looking for, please contact iTunes Store Support Team directly, using this specific link:--> Apple Support

Was it a subscription?

If the subscription isn't billed through Apple:

Don't see the subscription when you follow the steps to cancel your subscription? You might have purchased that subscription from another company.

On your bank statement, find the charge for the subscription. If your bank statement doesn't say Apple, apple.com/bill, or something similar, Apple doesn't provide this subscription to you. To cancel the subscription, contact the company that offers the subscription to you. Statements often list the name of the company, such as Hulu, Pandora, YouTube, Amazon, HBO, etc.
