Anna University — Login issue to apply Transcript online

I got admission to do my PG in Canada and the college wants the Transcript to be emailed to them directly by the awarding institute. I tried registering in Anna university Transcript online and it shows my student ID is already registered. I had registered in the website 1year back when doing WES evaluation. I tried to login with my old password but it showed invalid login.

I want my Transcript to be emailed as soon as possible otherwise my admission will get cancelled. Please help or suggest me an alternative option to apply for Transcript online.

I have sent emails to Anna university mentioning the issue thrice and tried calling several times. But didn't receive any response to emails neither picked the calls. Please help as this is really urgent and I am running out of time.
