As nobody should be victim of fraud, everyone should be aware. I wouldn't recommend green motion to any one. Especially Green Motion Heathrow. If you decide for any reason to rent with them make sure you take pictures of all documents and parts of the car you are renting as the staff will find a damage on the car that you haven't caused to take money from you. If you from abroad there is a big chance to be victim of this fraud. I experience it and been informed that it's frequently happening. It is better to pay a bit more with another car rental company as will end up pay a lot more with them. Contacting their customer services will be a wasre of time and won't be helpful to you. It's seems like the company is training their staff to make money by any means which is sad. The value of this company is scary. I am not surprised of know why customers doesn't rent with them again after their first experience.
