Dear sir / madam

With reference to the above mentioned subject, i would like to state that i am a customer of your respected bank having its branch at bali nagar, new delhi-110015. My account no. Is [protected]. I would like to complaint about the unauthorized debit of ecs for my saving bank account without my permission or knowledge and charging of interest and charges for the same.
I have taken a two vehicle loan form a private financier named hero fin corp in the month of august, 2014, whose ecs was supposed to be debited to my above mentioned bank account from september onwards. Unaware of the fact regarding submission of ecs mandate form i have not submitted the same with bank due to lack of details from my financier. The bank has not honoured my despite the availability of funds in my above mentioned account 20 ecs (Approax) out of a total of 24 ecs and charged me with ecs return charges over the period when the funds fell short. The suddenly without my knowledge and authorization the branch started honouring the ecs from april, 2016 onwards (Point to be brought into consideration is that ecs mandate from was never submitted by me to the branch). Due to which i have suffered a double loss of funds and my credit worthiness as i have been charged at both the ends. I have visited the branch several times by resolution was not provided at all.

The height of patience have exhausted when during this month the bank has honored the payment of rs. 200 and charged me with the ecs return charges regarding the above mentioned financier however, my loan has been completed in august, 2016. I have not availed any other loan or anything.

I am not able to understand how the bank has made the payment when no ecs mandate form has been submitted or with any instruction form my end.

Kindly look in to this matter and taken necessary action and provide me with a reasonable solution.
