Anna University — Anna University - Transcripts

I registered for requesting transcripts through online on Feb2. I tried to login with the password I set. It shows the message as "Login is invalid" from the day1. I am sending the mail to transcript enquiry on daily basis. I am not getting any response. Issue is also not resolved. One month has been gone. A hold has been placed on my account in the University where I am doing master. I cannot proceed the education till I submit the things required.
