Citibank Credit Card — Unexpected Bill

I am Mr. Raju Kanjilal an Citi Bank Credit Card holder since12/2008 and my card No. is [protected]. I paid all my outstanding dues that is minimum payment till June, 2009 from Jan, 2009 before due date but certainly Citi Bank Blocked my card and claiming to pay them all outstanding dues that is Rs.9000 which is impossible to pay at a time for me. I mailed to CitiBank several times that "please unblock my card and I'll use your card properly and I also pay the minimum amount due before due date every month in future to maintain a lifelong good relationship with you" but the responsed me rudely. I am ready to pay minimum amount due (5% on outstanding as per credit card policy) every month to CitiBank & I also wat to build a strong relationship with Citi Bank.

Thanking You
