I was unwittingly involved in what appears to be an insurance scam perpetrated by Raj at the Sixt Heathrow Terminal 2 pickup when I picked up the car. The vehicle had extensive damage to the rear and even though I was happy to take it as long as they documented it - Raj refused to do so and threatened to call the police if I took a photo of it with him in the photo as evidence. The damage was NOT listed in the contract. I got around the scam by emailing your office a photo of the damage BEFORE I drove the car away. Raj was acting like a lunatic and I am sure glad that I did what I did - because sure enough your organization blamed ME at the end of the rental for the damage. Anyone else would have not noticed when they picked up the car and would have been screwed. Its also a good footnote to mention that the vehicle was parked about 1 inch away from the metal barrier, which meant that it would have been impossible to see the damage - I believe this was done on purpose to hide the damage from a renter. I could not get the manager Emilio from Terminal 5 on the phone to discuss this matter, so I remain pretty disgusted by the whole event. Raj is an angry liability and he does your organization no favors. Given this - this is the last time I will be renting from you, it is just too much trouble after a long flight. It took 2 hours from start to finish and Raj made a number of threats and incorrect statements which I am happy to share with you if you are interested.
