Zoomcar — I'm complaining about worst service experienced

I have booked car for my trip from 1 March to 2 March on 21 Feb but on 28th Feb i get the notification that the car is unavailable and they didn't even had courtesy to arrange me some other car and the coustomer care support number doesn't receive my call i tried like 30 times in 3 days and even my 2500rs is stuck in this booking even after my trip is finished yesterday itself so if i dont get any support from zoomcar car in 24hrs then definitely i going to sue this company
