Zoomcar — Change of mobile number in the profile and contacting customer care

Address:

Bangalore

I booked a zoom car through their website through my email ID . The telephone number I had is old and not active anymore and hence logged in through my email ID . Now I am not able to do anything with my booking and it says go to the mobile app to cancel or reschedule . I obviously cannot login through the mobile app since my number is not active for OTP and it wont allow to login through the email ID . I am not able to also change my telephone number to the new one . There is no customer care number and no other option to contact zoomcar
