Ikfw — Not fair asking more money for finale round

Hi, i got call and msg from ikfw to register for season 9, then i have registered and paid Rs 2536, at the time of registration they mentioned it's for all auditions, workshop and finale and now recieved msg like i need to pay 10000rs for finals as my kid is selected in auditions, what the hell it is. Is any person can pay only for auditions it is just fraud, i want my money back.
