Bank
Credit card used by someone else

Hi,

I have applied for housing loan and i get to know that i hold a credit card from a bank and i need to pay outstanding amount. I have never applied for any credit card except from ICICI Bank and i already cancelled that card. Now i am not holding any credit card but someone is still using my card using my identity. Please suggest what to do in this case? I don't have any credit card with me now. Please suggest.
