Hello Aspirant,

I regret to inform you that it might create some problems with your application form as a signature should be uploaded horizontally.

You don't need to worry you can visit the official website of AU and click the link mentioned as "grievance form".

Download the form and take a print out and fill up the incorrect details along with correct details. You have to fill a declaration form after it. Scan these forms and mail them to the given mail id.

I hope it helps.

Thank you
