Study / Application deadline for the study, payment method; UNIVERSITY OF WARSAW [8]

Hello everybody. I am from Azerbaijan and i would like to apply to the University of Warsaw - International Relationsö bachelor's degree (first cycle)

But i need a help about two things. First i could not find when is the deadline for international applications. The second, in the application system, it is written to pay 80 PLN via bank. But there is no such a section where i can register my bank account. If i go to the bank and transfer money to the given account, how they can understood that it is exactly me not someone else?
