From January 2022 a charge of £9.99 was taken out of my debit account. I do not recognise the charge. I cannot find it in subscriptions or purchases. How can I find out what the charge is for?

From January 2022 a charge of £9.99 was taken out of my my debit account. The charge is from Apple and includes several numbers and letter as a reference. I do not recognise the charge or what it is for. I have checked subscriptions and purchases in my Apple account but it is not listed there. I have three Apple devices and a check was made of subscriptions and purchase on each device but nothing listed for £9.99. Has any member experienced the same or similar charge to their bank account and if so is there a way to find out what the charge is for?
