I rented a car in July 2019 at LHR office. When we came to pick up the car there were 6 or 7 people in a queue before us, so we were waiting for more than 1,5 hour. The agent at the counter spent another half an hour to fill in all the forms and scan the docs. During the trip and at checkout everything was okay. One month after Green Motion communicated that they received a parking fine, and they charged me around 80 GBP (!) just to advise the traffic police my contact details to re-assign the fine. Okay. But in a week Green Motion charged me another 80 GBP to deal with the same fine, just because the road police mistakenly issued the same fine again. Instead of checking everything properly (I think it's not hard for 80 GBP fee), Green Motion formaly forwarded my contact details to police again and charged another 80 GBP for it. When I contacted them to clarify the situation, the answer was I should contact the traffic police to withdraw the second fine - can you imagine?! And that they will only release the money when they receive notification the fine is cancelled. But the 80*2 GBP was not charged to settle the fine, but just to handle the request! I would never deal with this company again.
