Cognizant Technology Solutions — Error occurred at re-submission of PAN card details

Address: coimbatur

I got selected in cognizant technology solution as programmer trainee. I have submitted all my details in the pre-joining formality portal. But an error occurred in typing my PAN card number. I would like to modify the given details and want to correct it. I mailed this to my HR but they only receive specific mails. I want to modify it as soon as possible.
