Zoom Car — Deactivate my zoomcar account

I have raised request in zoomcar app several times to change my registered email id because the one i am using is misused by some people. If you do not have an option to change emailid associated with zoomcar account, at least delete or deactivate my zoomcar account so that no one logs in with my credentials. This is a basic feature that if someone wants to deactivate their account, they must be given an option to do so
