Cheap Car Hire in San Blas-Canillejas, Madrid from ₹ 425

If I have to leave a deposit, I would like to know its exact size BEFORE buying the service. I had to cancel because I didn't have enough money freed, and even when I cancelled almost immediately I was billed the full rental. I will not trust Centaur ever again

I have rented cars throughout many countries in the world and this has to be the absolute worse experience of the last 35 years. I had booked an SUV, but the SUV had a bad sensor so I could not take that vehicle. Instead, they gave me a small sedan (Corolla). When I asked for another SUV because that is what I paid for, they said that it was big enough and had no other SUVs available even though I saw several in the parking lot. They charged 50% fee of total rental for 1 day in France which was never disclosed when booking. The 50% of total rental did not include insurance or anything else so I was still responsible for any damage, so the extra fee was a complete money grab. What was I to do as it was too late to book a vehicle with another company in another country? The only positive was the fast return of the vehicle.
