I came to know about this site just three weeks before. I tested this site
If we are goint to take rent a car from carzonrent.com we will get the cars that not in good condition or like damaged cars.
They are expensive when compered Other rental car services.
Their site is also not well organised form. Which may make coustomer What to do in that.
The carzonrent.com service is aslo so poor. If we call any support team for any help they will not respond sometimes. If they responds also they will take the action against it will be too late
