HDFC Bank — Credit card issued without my permission

Address: Bangalore, Karnataka, 560100

I am too much frustrated with your process of credit card application, it's been over 8 weeks since i have applied for the credit card. But you guys are having some or the other issue every now and then. Today i received an email that "you already have a hdfc credit card issued on your name so your current application is put on hold." fraud alert!!!
Now, when i don't have any credit card (Any bank/subsidiary) issued on my name so far and i get this email from you, i have no other choice than moving to police for help. I want you guys to furnish me the credit card number which is issued on my name or i will move to court for the reason that you guys have issued a credit card on my identity to someone else without my information. This is serious now.
And even your employees have created my bank account with hdfc with wrong date of birth (They interchanged the month and the date). Pathetic!!
