[Resolved]  ICICI Bank Car Loan — EMI debidet twice in same month, not refunded even after one month

I am having a car loan account number LAALD[protected] in ICICI Bank for which the ECS is being debited on 10th day of every month from my account number[protected] in ICICI Bank. During Jan 2010 the ECS returned due to my salary coming late, for which ICICI Bank Car Loan department raised a conversation and got collected a cheque number 483389 for Rs 4873 from me, the denomination being as follows ( ECS amount Rs. 4648 and ECS Bouncing Charges Rs.275), and issued me a receipt for the same. Later in the month the aforesaid cheque was presented in the account and cleared, and alongwith this the ECS for Jan-10 was re debited into my account, thus debiting a total amount of Rs.9521/ in place of Rs.4873. As an impact of this negligence from Bank's side my cheque for Life Insurance Premium got bounced and the policy got lapsed. Moreover, when the issue was highlighted to the Bank's concerned department I was assured that the amount that has been debited by mistake will be credited to my account in next 48 hours, but now today even after more than 20 days of the previous conversation the wrongly debited amount has not been credited back into my account.
Due to negligence of the bank I had a loss of reputation, problems in reinstating my lapsed policy, and also interest loss on the amount not refunded to me by the bank in a reasonable time span.
