JustDial.com — Unethical behaviour related to ECS

I made a agreement to justdial within 15 days i asked to stop the service due to irrelevant and spam services i was getting and i clearly mentioned. No ECS to be triggered to my bank account . Even after that they trigerred the ECS for 6 times in 25 day period and now if i ask them they say we are not responsible as future ECS has been stopped now i got a deduction of Rs.3500 from my bank due to ECS Failure. Which i many times informed the company to stop the procedure from 15th day of commencement and they took deposit of 9720/- and now they wont even return the deposit and now they are saying we cant give the money back. In these past 35 days i am mentally disturbed so much and bearing the penalties from my bank of 3500Rs. Which is not acceptable
