ICICI Bank — credit card issue - urgently

Dear team,

Few months ago someone called me for icici credit card, they offered me for free of cost credit card without any charges hence i applied for the credit card, however i have received credit card and not the security pin, i have not used this credit card and i had started to receive text from icici that my outstanding amount is rs. 5000?-, i am worried without receiving credit card pin how the statement generated rs.5000/-, are icici bank doing fraud with customers to earn money?, how this is possible without using credit card statement is generating rs.5000/-, please take this matter on top priority as it is directly impacting on my cibil score.

Credit card number: [protected]

Please block and discontinue credit card as i don't used it and secure pin is not delivered to me.

Thank you,
Nilesh phadtare
