Zoomcar — My reservation

I had booked zoom car in 1st march but I never received it, as the car was not at the location, and driver and executive phone number was switched off since I got them . I tried to call customer around 40 times and waited for 20 mins but no response . The main problem is, that they think I have the car and I’m not returning. I am done with zoom car and I would rather walk than ever book zoom car in my life .
