Adobe has a different plan nowadays. It's based on monthly payment and recurring payments. That means if you purchased a month of access for a specific product and forgot to disable the Auto-Renewal, then the system will automatically deduct money from your credit card or from the payment method attached on your account.
Log-in to your account on Adobe's website or contact the bank and explain the situation. It might be possible to obtain a refund if you forgot to turn on the option.
