JustDial.com — ECS Mandate wont stop after multiple calls

I had placed a request to stop my ECS to Justdial in September. They said that I had serve a notice period of 90 days. This was the mail that I received from JD -
‘Dear Customer
We have received your ECS Stop request on (15/09/2021) and we have accepted your notice for termination of ECS. Your notice period ends on (15/12/2021).’
I did that and called them again in December. The ECS dept executive said that you should’ve called in November, now you will have to do another 90 days. I argued regarding the same so she said she will change it to 30 days. I called back multiple times after 30 days. They won’t connect me to the ECS dept.
I was not charged in January for the same so I thought they have stopped the ECS mandate. But today I received a call that my payment to JD wasn’t successful and I have to do it manually. I told them the notice period is over. The reply was ‘another 30 days’.
I told them that this is high time and I will take this to consumer court. The reply was ‘sure, you can do that.’
I would really appreciate if someone helped me out in this scenario. I have no hopes from JD anymore.
