Payment

why apple.com withdraws cash from the card? I do not have active subscriptions (checked in settings) and did not buy anything from App Store for long time, but today I lost money from my card and was billed for Apple iTunes com and do not know what for I paid, no receipts received or detailed description of purchased items. Only can see from bank statement that receiver of transfer is Apple bill. Could you please help to understand the situation and explain why I Should pay for items I do not know even
