I hired a car from Green Motion at Manchester Airport in February 2011. When I picked the car up I was told that I had to leave a 750 pound security deposite, refundable on return of the car without damage. According to the web site this amount should have just been held against my credit card, not debited. I returned the car with no more damage than already noted prior to hire, and had my return form signed to that effect. I was told my deposit would be released within 3 days. This was 7th March. By the time I got my credit card statement 3 weeks later, the amount was still on the card. I tried to contact Green Motion accounts department. Eventually someone answered the phone and said they would have to call me back. They never did. Now they just don't answer the phone. Emails to Green Motion just result in a recommendation to get a charge back via my credit card company, but the accounts department never responds to any emails at all. This will take about 2 months in total, meanwhile I have had to pay my credit card bill. We've had no correspondence from Green Motion saying they have any reason to keep the money. It simply amounts to fraud & theft. I would advise anyone against using Green Motion at any depot.
