Zoomcar — Car not delivered

Travelled from Kerala for 1 week vacation with two senior citizens parents, and my 2 toddler kids. Zoom car status showed car ready at paschal vihar delhi and traveled there and found out car is not there. Waited in the street for two hours with the kids and parents and found out previous person didn’t place the car. Zoom car customer care team responded very irresponsibly and didn’t provide any guidance on except saying they will give a call back. Resulted us get stranded in the road for next 2 hours with luggage’s and parents. Spoiled entire vacation
