[Resolved]  State Bank of India — phone harrasement even after payment of bill within due date

sir,
i dropped cheque no.50231 of sbi, anna nagar, chennai-40 dated 18/12/2008 towards credit card bill payment of Rs.1878/-on 18/12/2008 itself and the same was encashed on 20/12/2008. I could not get my passbook updated immediatley.Ever since 21st Dec, I have been repeatedly getting calls from collection agents of sbi credit card asking me to pay the dues immediately.Initially i said i had not updated the passbook. then after 2 days i gave them the cheque no and date. i also told them my account has been debited for the said amount, In spite of all this, till today every day morning at 8 o'clock and again at 6 in the evening i am getting calls, they are not ready to verify the records. like parrots they are repeating the same message, I am sick and tired of them. I request you to stop them from calling me at once. Otherwise i will simply cut the card and drop it in the box. I will not be a sbi subscriber anymore,
