it sounds like this is the result of a head-on with a curb. If so, it's not really a framebuilder issue, or at least most framebuilders will not touch the repair. If you really want to repair it, you can probably find someone with one of the old Park frame jacks. I never had a lot of luck with those, but I probably only used them on heavier bikes. A lightweight bike probably will straighten out a lot better.
