Hello @burakutkuuu and welcome to the community!
A temporary charge goes through even if the student verification was successful or not. But it is only temporary charge on your credit card and they should disappear in a few days.
The only charge that you actually have to pay for is if you were successfully verified for the student discount.
The verification process takes a while, so please wait a few days.
Feel free to contact me if you need any further information
Have a nice day 🙂
