Cannot get link for contact to work. Rescue email address is no longer valid and I cannot remember my security questions to update it

I cannot make any more iTunes or Apps purchases because I cannot remember my security questions. I have read online that you cannot update rescue email address (mine is no longer valid) until you answer the security questions. I have clicked on the link for support on account management but it never opens. I am very upset because all I am needing to do is make purchases. Any ideas or numbers or actual links you can post in response is appreciated.
