i had the same problem with revolution, they took my money, asked me to sign a disclaimer and told me to raise my car.
also i had asked them TWICE that the steering wheel wasnt straight and it was either left or made worse.
i really wouldnt bother with them they seem to have all the gear but no idea!
im busy trying to convince my lass to go down to scarbourgh for the weekend because thats the nearest WIM approved place! well or edinburgh.
ive given up looking tbh but if you find somewhere local that isnt totally incompetent then give me a shout!
