Zoom Car — subscription extension

Company has extended the subscription from 6 months without my will and permission. I somehow managed to complete the money sucking subscription costing me approx 26000 INR approx. Now when there is time to take the car back this company is cheating me.
This is in relation to the 6 months tenure subscription with the Zoomcar. I never got a support from the customer support but I dont mind that. The issue is with the Insta pay that made me attach my credit card with the account and gave right to Zoomcar to deduct the amount on monthly basis without my permission.
The subscription ended on 30th Nov 2019 but I got an email from them regarding the extension of the tenure without my permission or intimation.
I wrote to them and after multiple emails they took the car back from me. On asking regarding the security deposit, they replied to give it back to me after one month. and now they are sending me the statement where the subscription charges of December 2019 are also added. And there is nothing written in relation to the security deposit.
This is really a fraud company and the thing is that we are in India where such companies nourish a lot.
If I requested to get Instapay removed and hence to disconnect my credit card- I was told to send 10000 INR for doing the same. I am having each and every proof with me. The emails and the messages I sent to them on facebook and twitter page
