ABN AMRO Credit Card — NO STATEMENTS

Hi,
I have not been receiving any statements/bills for my card since months. The collection agency has been calling at my residence and asking me to pay the due amount of Rs. 2000 every month. I have been regularly paying that amount. However I recently got a call that my outstanding was Rs.74000.00 . They said the intrest got accumulated since you have been not paying the full amount. I am in a soup for no fault of mine. I told the agency to submit me the remaining statements. They say they are not in the position to do so. Please help.
