My Sam's post did the same thing. I used a snap punch to create a "grid" of punches about a centimeter wide in the area of the clamp. Punches were about 2-3 mm apart. After a bit of sanding with some fine sandpaper the fit got just about perfect. I wound up with some of the scratching exposed, not real attractive but functional. I spent about an hour on this. Post hasn't slipped since.
