Jefferies Farm Trade Centre - Unbeatable Car Supermarket

The sales staff are friendly and compared to most car places aren't particularly pushy. My problems didn't start until after I'd bought a car. About one month after I'd taken ownership of the car it lost power whist I was travelling at 70 mph on the M25. I managed to make it across to the hard shoulder but I had to take my chances by coasting between the lorries and other traffic. UnbeatableCar agreed to look at the car and see if they could repair it, it was within their warranty. However they then had it for almost 8 weeks. During which time I was persistantly told it just needed one more thing fixed and then generaly when I called them. Then it ended up having to go to the main dealer for more repairs. To date they have not diagnosed the problem or told me what they have done to repair it. I tried asking for a refund but they would not even consider it. I was told that I had to ask in writing for any information on what work had been done, though I have been doing so for some time I am now being told that no fault was found and no work done. Very poor post-sales service. I would not recommend purchasing a car here to anyone. Avoid at all costs.
