Non receipt of admit card

Sir,
     I have received a letter from institute, mentioning that-
     "It is noticed that we have not received the copy of your online examination form due to which your admit card does not bear your photograph. You are therefore requested to send the copy of the form along with the photograph for our records."
     But I have not received any such admit card yet. And I have already sent the examination form around 1 month ago by speed post on 18.03.2011...
     Kindly help me what i am required to do now? I hav downloaded the admit card from icai.nic.in.
     Please reply....
     Waiting for your suggestion...
