A month ago I gave Car Jet 5 stars for ease of booking since then I have picked up and returned my car and can now give a full review. I now give them 2 stars and would not recommend them for the following reasons: 1) The shuttle information. To the car rental pick up point at Heathrow is wrong and this delayed us 1 1/2 hours and we had to catch a cab. 2) We had to change our holiday plans in UK and leave for France earlier than expected and had the following problems: A) The Carjet web site does not allow you to schedule an early return. B) It was impossible to get an answer from the Customer Service number or leave a message. Phone calls simply do not complete. C) Nobody answered the telephone number for the Heathrow dealership either. D) I emailed Customer Services but only got an automated reply saying it would be referred to the manager. E) I, therefore, drove the car to the Easirent dealership and it was closed at 10:30 pm. The website says it is open until 00:30 am. F) There was no Drop Box. G) The Moxi hotel would not take the key and said this happens alot and people simply leave their cars in the Car park H) I, therefore, put my keys in an envelope and placed it on the dashboard for Easirent in the morning. I) I emailed Customer Services telling them what I had done and where they could find the car. J) I got another automated reply. K) Having not got a closing invoice I was concerned that the car could have been stolen so emailed Customer Service yet again. No reply. L) So deeply concerned one week later I called Easirent and got through. Fortunately the car was still there 1 week later and my account is closed. Though Car Jet advertise that you can return the car at any time this is difficult and they will not refund you even in the most extraneous of circumstances. All round a bad choice for me. Price is not everything.
