ICICI Bank — Ecsrtnchg after emi payment

I had an EMI of Rs.2499 which was due on 5/10/2020. The EMI had bounced due to insufficient balance. After that my ECSRTNCHG were deducted from my account without prior notice. Afterwards i received a message to maintain sufficient amount for EMI deduction, which i did but the amount was not deducted on that same day. Then again an ECS was deducted from my account. A total of Rs.1800 hundred were deducted from my account by ECS till now. After talking with the executive of the Finance Company i paid the EMI due but still the ecs amount is being deducted every day. A total of 2100 has been deducted would like to get it back since you've deducted thrice of the amount actually needed to be deducted kindly look into it revert and refund the amount.
