This is not a car rental business, it's an insurance rip-off.

First of all they didnt have the ford focus I asked for, the man informed me they only had one which wasnt in use at the moment and havent been in use for some time.I didnt feel comfortable driving the clio so I asked for it to be change the man cleaning the car had no problem with this however the man on the desk did and started arguing with his colleague right for front of me he was very aggressive and unprofessional and it was quite scary to be honest

The car was unavailable when I reached there. Staff is more abusive then a nazi concentration camp

Nothing particularly wrong, certainly value wise. Staff friendly enough, car fine, service good. A couple of things to tighten up on though (some my misunderstandings but you could help others avoid)... Finding the location - I'd wrongly gone to the car hire bus stop at terminal 5 before realising you weren't on there. When I looked on the internet at the booking it said at the top 'available from terminals 1 -4'. As I saw that I didn't look further assuming I needed to go to a different terminal. I did so on the free train then found you weren't on that sign either. Only then did I look at the smaller print and find I needed to go to a specific bus stop for a specific bus. By that time it was very late. I had tried calling for advice several times but no one picked up which would also have saved me time. In hindsight I completely realise that it says on the detailed part of the voucher how to get to you but having travelled mainly abroad I'm used to car hire that's signed or in the airport. It never crossed my mind not to just follow signs for car hire and look for your desk.

VERY slow pick up process, staff tried to limit mileage to 100 miles per day despite car being booked with unlimited mileage. Still waiting for fuel deposit refund.

Excellent!
