HDFC Bank — Deducted amount of my blocked card

I took the HDFC credit card in the year of 2006 and blocked in the same year. I never used this HDFC Credit Card for any transactions. The HDFC credit card deparment themselves purchased “Bajaj Life Insurance policy” on March’2009 without informing to me or my approvals for the blocked card. Then HDFC Credit card division deducted amount of Rs.7245.77 from my HDFC Savings A/c on Nov'2009. I came to know all these transactions once the amount deducted from my Savings Account.

Could you please help me to get my amount back?
