Account Recover

I used to login using my email id to my account tcs_bhediya since the beginning. Although the email associated with my account tcs_bhediya was not the same as the email I used to login, but still I used to get logged in that account (hence I never bothered to change the email id linked with my account, my bad). But few days ago, when I tried to login using that gmail, it didn’t login to tcs_bhediya. That email used in my original account is old, and I don’t remember its password (can’t recover since google says not enough info). I’ve emailed codechef but received no response. Please do something man. It’s genuine. Please change the email id in my account to the current gmail I have.
