Get your money back if you can. If you can't and choose to fix it, the wiring is an easy fix. I don't see the ski jump in your pics but that doesn't mean it isn't there. If no ski jump, there is enough meat on those frets to level them down to the bottom of the grooves. It will be a greasy playing daddy if done right but there is no room for error and having them leveled again later. I wouldn't refinish the neck. Maybe smooth it out a little and get used to it.
If it has a ski jump, put a replacement neck on it until you can find someone competent enough to lift the fretboard and plane the neck then reinstall it. If no ski jump but the truss rod is maxed out, remove the nut and put washer(s) under it and see if that gives you some play.
I've had several 70s P-Basses over the years with all the associated problems. Good luck.
