The comments by Ford and ATS sound like you're being fobbed off. The camber in the road is true to a degree but that still doesn't explain why the car pulling to the left is worse than any other car or why you're getting uneven tyre wear. The next thing I would try is a 4 wheel alignment incase it's the rear wheels that are out of line and are pushing the car to the left - see the thrust angle section of the following web site for a very basic overview http://www.familycar.com/alignment.htm
