Mobile one year Pro license, I had error occurred in the payment of 5.5 million Korean won (5000$). What's the cause?

I just purchased a one-year pro license. The price is 55,000 won (50 dollars). But as soon as I made the payment, the Samsung Card security company called me to confirm that I paid 5.5 million won (5,000 dollars) in Kaspersky and blocked it. After that, it was automatically re-paid at 55,000 won. Why did the payment of 5.5 million won occur? In the UI I saw, there was no purchase option except for a year's worth of payment.
