I am CA final student registered on October 23,2009. Along with final registration forms I have enclosed Form 112 for studying additional course. I have received acknowledgement for final registration and fees payment on 28th and 23rd of October.But I have not received the permission letter to study additional course and student ID card till now. So what should I do to get my permission letter to study additional course and student ID card. I have sent freequent reminders to institute through mail and letter. But no reply from the institute.Then what should I do now ???
