Zoomcar — Non-availability of car booked with full fare, Wrong information of car locations, incorrect trip starting times, wrongful charges

I had reserved a car for a trip from Chennai on the 6th of May, 2023. The start of the trip was scheduled at 4pm. However, due to delays in travel, I was an hour late.
On arrival at the specified location, the car was not found. I spoke to the host(Mr, Asgar Basha) over phone and he told me that the car would not be available till 9PM since he had sent the car for servicing. He was also quite rude about the whole conversation arguing that he had no responsibility to inform me that the car would not be available even if i had paid the full fare and booked the car.
I reported the issue to the customer care official following which i was offered the option to select a second car. Luckily there was another car available just 1.5km from our location. I immediately booked it with an additional payment of Rs. 428. I got to the second location at my own expense and called the new host.
He informed me that the car is at another location around 18km away and that i could take the car if i got there(apparently the location was not updated in the app although the host had informed the company). I spent the next 1 hour and 1000 rupees travelling in an auto to the other side of the city. I finally received a car and could start my trip at 7:10pm.
The Customer care official who i spoke to then mentioned that the trip starting time would be updated to when I get the car, but in the final bill, it was 2 hours prior to the time i received the car. Despite this, i was charged a late return fine for a 40 minute delay.
Interestingly, after the end of the trip there is no way to speak to a customer care official in Zoomcar and you are limited to automated chatbots. In spite of raising tickets regarding the charges, i have been getting incessant messages asking me to pay my outstanding amount, including threatening messages this morning. Still no response to the tickets.
