You may be able to adjust the intonation at the saddle. If it is sharp the point where the string contacts the saddle needs to move back away from the nut. It may be best to take it to a music store or guitar technician or luthier.
Or if you are brave you can try to adjust the saddle with sandpaper attatched to something hard and FLAT. If you do it yourself adjust it SLOWLY, little by little. And pay attention to how much you are lowering the action in the process.
It should be able to be fixed.
Good luck,
Thomas
