JustDial.com — ECS cheques are issued even after cancellation

I availed Justdial's service for my hostel in chennai. Due to corona I was forced to close it by this years's February. So right from March I have been sending mails and called Justdial several times for stopping the ECS cheques issued as I foregone their service. I repeatedly called their executives who helped me during availing of their service. As a result I am being charged every month for ECS cheques bounce charge and my cibil score dropped. I keep no balance in my account since if I keep it's getting autodebited by Justdial. They are stealing money even after I got a message saying ecs stopped. Kindly help me
