I had a bit bad experience with Zoom car too.
Since I had a bit bad experience wiht MILES I choose Zoom car for my next trip. One of my friend who booked the car for our weekend trip and while taking the car the petrol was only 30% to 40% in it and they noted all the dunts if they had any and details of the car including petrol and they gave one copy to us.
We started our trip and had loads of fun in travel and as well as the places that we visited. While returning, after completion of almost 60% of the journey the tank was almost empty so we thought to fill it back and we went to petrol bunk and filled the petrol. Here is the main mistake that we did is we filled the tank full instead we would have filled half or something like that.
So after reaching the Zoom Cars the petrom was almost 60-70 percentage. So while returning we had informed him that we had filled the tank full and now the petrol is almost 70% which is double the petrol that we got. But he refused to pay the cost of petrol and he is saying you can take the car and roam around and return it back when it come to 30-40%. Which is really bad in terms of customer satisfaction.
Since they clearly written in paper saying there was only 30-40% of petrol in car not more than that so thay have to accept the 40% extra fuel in car and atleast pay half of the amount. We felt really bad regarding the same.
I recommend people to take car with full tank which is really better while returning the car.
