[Resolved]  Citibank Credit Card — unwanted card statements after cancellation

This is with reference to my Citibank credit card ; i had been using this card since 1997 regularly with no issues as I had been paying my dues on time; till 2006 when I was been approched to have a birla sun life insurance policy where the premium's go thru' my credit card for payment. As agreed for the frequency of instalments; this was not been picked up by citibank and they debited my card 2 times in one quater which was a mistake ; I kept calling them till Sept 2007 to reverse the debit as it was a mistake but this was not reversed and I was been charged on my statement for interest for no mistake of mine. I checked with Birla sun life for the payment recieved from citibank and made the same amount of payment to Citibank. Since this issue in 2006 when they debited my card twice; I never used my card for any other transcation. Finally after taking to 10 people on customer service line for several times ; I gave up and wrote a letter expalining the entire situation; had cut my card in two peices and send it to Chennai office of Citibank Credit card by Register AD .. I got a reciept of this. But till dat ein 2009 these credit card statemenst haven't stopped to be generated and keep coming; at the same time I am going thru' the hassle of facing the contract agency on behalf of Citibank to explain every time that there is no due on my side to Pay. This is absolutely frustrating and getting no where...can some one action in citibank based on my register AD in 2007 and close this once for all...I am not paying a single peny to them ..but whereas I demand for the hassle I had gone thru' in these 3 years compensation for myself ...that was all due to citibank mistake.
