Refund Apple services via paypal

Hi, I accidentally signed up for subscription which i do not want. The payment was collected via PayPal and the money taken from my account 17th April. The PayPal receipt shows this was paid to Apple services.

I have tried to claim a refund via PayPal however they will not agree to this. When I try to claim through Apple it says I need to click on the transaction via my Apple account however it isn’t showing on there.

Is there a delay on when this will show? It’s over one hundred pounds so this is really stressing me out!

I really appreciate any help, thank you.
