JustDial.com — unauthorised ecs deduction

I got registered for with just dial few months back. They asked me for a cheque to start website (Ayurhut beauty and wellness) telling me that i only have to pay only rs 3540/and they asked me to sign documents. I was not aware of the ecs process neither did the agent (Mohak) told me about it.. Then all of sudden i found out that every month the same amount of rs3540/- is deducting from my account. After this i called just dial customer care and then i got a call from one of just dial agent named as from delhi... He told me that it is not possible to cancel the contract.. I told him that i didn't signed any contract regarding ecs but he told me that i have to continue this service. When i told him that i am not willing to continue this service he just started giving me lame excuses. Even during lock down they deducted amount from my account. This is how they are looting people. Even though my website is unpublished but still they are deducting money. Please tell me how to stop this was service.
