Vehicle damaged at Basil Green Ford!

My vehicle was taken in for a fuel pump repair, on the day of collection we arrived and the vehicle had been damaged!. The driver from the washbay area and reversed the vehicle into a pole and damaged our boot door and tyre cover to the point where is has to be replaced. Ford did not bother to notify us of this until we had arrived! They have not taken any responsibility and have blamed the washbay company. It took over a week for the assessor to arrive, then again no feedback until we sent emails. All this time Ford has remained silent and not even a courtesy mail. To today ,my vehicle has still not been repaired.
