Charged by Apple on my bank card but I haven't made a purchase. How can I find out what the charges were for?

So, Apple has charged my card £99.99 which the bank tried to block but it eventually went through after multiple attempts from Apple. There was another transaction for £62.99 which was blocked by the bank. Both of these amounts are don't match up with any subscriptions I currently (or have ever) had with Apple. I'm guessing this is a case of card fraud.

My question is, how can I find out what those charges were for and how can I get back the £99.99 taken from my card? The bank says It's Apples issue.
