Elephant filthed me over with a similar thing.

I repeatedly told them that the golf I had was the anniversary model and they gave me the quote, then sent the docs through without the magic word "anniversary" on them. I called them up and explained their cock up which took a while as clearly they don't understand anything about cars, and they then had the cheek to charge me an extra £250!!!

I got my money back in the end and would never use them again, total bunch of jokers.
