ICICI Bank — Fraud case regarding credit card

Address:

Kolkata, West Bengal

From my ICICI Credit Card, had bought an object costing Rs 8400/-and I got to know the same from the monthly statement of the bank. I reported the same at the Lake Town Branch (Kolkata). They blocked my card & suggested to report to Police Station regarding this fraud case. I didi the same & lodged a G.D. Still I am getting the monthly Statement with enhanced amount of interest. Recently I called up Customer Care & they told they won't be able to help me without a FIR. Now the Lake Town Police Station is not taking the FIR.
Please Help.
