Akbar Travels Of India — Cheating by providing a different vehicle.

I went to Akbar Travels at the Arrival (T2) of Mumbai Airport for hiring Innova upto Mumbai Central on June 18, 2022. I was charged Rs.2000 and bill number 181225 was provided by the travel agency. Thereafter, I was told to go to P4 of Mumbai Airport to board the Taxi. Upon reaching P4, I was told by Akbar Travels that there is no Innova and only Ertiga will be provided instead.
I was forced to take Ertiga as there was no way to go back again to Akbar Travels located at the arrival lounge of the airport.
This is cheating and Akbar Travels should refund the excess money charged to me.
