Cognizant Technology Solutions — forgot the login credentials for my food card

I want to Login to Food card portal of HDFC bank.
I have Forgotten my credential details (i.e) Login Password
I know my card details, CVV number, DOB, Expiry date. But I have forgotten my User Id.
Can you help me to reset my Password. For security Purpose You can send me the reset Password to my registered e-mail Id. So I can Login and see my Transaction.

Also I am not able to open the Monthly Statements sent by HDFC to my registered details.

Please resolve my request, also provide my "point of Contact Number", So i may feel comfortable to resolve my issue
