DO NOT BOOK!!! Long story short, we arrived back at Heathrow to be told our car key was missing. I kept ringing them back every 5 minutes to ask for an update to be told they were still looking and that they would call us back. After many phone calls of them not answering or putting us on hold they informed us that another driver had moved our car and then left our car key in another customers car who had since drove home to Newcastle Upon Tyne. We reported it to the police and they marked it as stolen. The company said they would reimburse us for travelling home, refund us for the parking and deliver our car to our home address. The next day we received a call from the police to say our car had been flagged up on the cameras and was found by the police abandoned in a side road a mile from Heathrow. The police recovered it and impounded it at Heathrow station. We then had to drive 3 hours back to London to pick it up and we had to pay £150 to get it out of the impound. Fortunately it was not damaged inside or out, it still had fuel, no significant extra miles on the clock and they had left the key on the tyre. I have never heard back from the company and I am now £400 out of pocket. These people are scammers so please DO NOT BOOK!
