Money taken out of account.

Hello, I have been having trouble with apple payments. Every month on a random date apple take 9.99 out of my account however on my subscriptions page on my settings I am not subscribed to anything. Eg. Apple Music o Apple Pay I do not use anything linked to apple that would cost me 9.99 a month. 4 payments have been taken out of my bank account I can send proof of this. I was just wondering is there any way I can get my money back and cancel this, I am not subscribed so I don’t understand why the money is being taken out I would really appreciate if you could help me.
