Zestmoney — My PAN is added to unknown Zest account

My PAN is added to unknown Zest account and there is loan with that and its effecting my CIBIL score,

I request you to close my account and take necessary action against that person,

I have already sent mail to you guys and you people are asking for registered mail ID, how the hell do I know registered mail ID??

are you guys dumb or what, why don't you run a company properly?
If you can't run just close the company, why are you cheating people??

I'm providing proper details again, check and close my account.
