JustDial.com — ECS not stopped inspite of several complaints

Hi..I am a Dr. opted for just dial service for leads for my clinic dentamax superspeciality dental care, kolkata. I have signed the ecs mandate for 1 yeAr but they are deducting the amount since 3 years. I told them to stop the ecs and service but they have got deaf ears. How come a company run the ecs like this for 3 years without my consent?its a fraud company. Inspite of mail and calls they are reluctant to stop my ecs. I dnt know how a fraud company like this is doing a business in india. PleAse dont avail the service of just dial
