Very dissatisfied. The provided car did not match the booked model. I booked a Sharan, but got a Citroen Picasso C4 instead. They claimed it was the same class, but their attitude was irresponsible. It took five hours of negotiation at pickup, delaying our trip.

Staff were slow and inefficient, even when there were 20 people waiting to rent a car. They threatened to force us to buy their full insurance by saying there would be no assistance otherwise. They charged the card without explaining the amount and were unwilling to explain why they needed to pre-authorize £1250. Their attitude was very unfriendly.

High pre-authorization amount, and won't allow the use of multiple credit cards

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.

On arrival was offered a GLA this is NOT an equivalent car or 'upgrade' as they later told me. I booked a V60 Estate or Similar, I expected something similar to this, there was no cars in their car park remotely close to this model. An upgrade was given but still not an estate and after a long discussion.
