Please dont skip this, my IGN is IcySoulz on minecraft and I have a problem with account security questoons, its a bug.

Dear Mojang,

Please don't skip this. I don't know where the help center is so I came here... My mojang account is IcySoulz and I am trying to change my account name and Minecraft skin. I have been trying to do this for a few months but I can't get into my account because I forgot the security question answers... I have pressed send email and it sent an email to the account email but it keeps asking for security questions... how can I fix this?

Please get back quick, thank you
Dylan / IcySoulz
