I have not answered security questions when I was registering

So I was making a new Apple ID account when I got an Iphone. I used email ****@gmail.com to register. I don't know how but not once did Iphone ask me to answer security questions, but keeps asking me for answers every time I try to log into my account or make any change. I cannot reset these questions since I can't log into my account. I can't do anything. I can't call support since I am located in Serbia and there is no support for this country. Can you please help me? I would like to delete that account and add that email to the one that I am using right now.
