Tamil Nadu Public Service Commission [TNPSC] — "Already validated with different account"

I am A. Benazir. I registered in OTR few months back and also linked my aadhaar number . Without the knowledge of applying before, I created another account and when it asked to link my aadhaar number, it showed as already registered. Now, I cant remember loginid or password. When i went into the forget id option and gave my details, it shows the current id.

I request you to recover my old account which I linked my aadhaar to or atleast tell me what I should do to deactivate my current account so i can recover my old one.
