[Resolved]  Credit Card — closure of account

I had a Citibank Credit Card No. [protected] I had surrendered this card and asked citibank to settle the account -- I received an offer from citibank for an amount of rs. 8200.00 vide their letter dated 10th sept.2008 -- accordingly i cleared this amount in one instalment vide cheque no. 158867 dated 24.9.2008 and the agent handed a receipt as token of clearance -- to my surprise they have again come for a payment for the entire 1 year interest for non payment of credit card --

I am very much confused and handed over the copy of respective letters to the agent -- I request your offices to please go through the same and give me a clean chit as soon as possible failing which i shall take legal action --
