did you try alternating, heat then penetrating oil such as Blaster or Kroil?
If all else fails, grind the face flat (not flush.....flat). Use a center punch to mark center. start with small 1/8" drill, then progressively use larger drills until you stop 1-2 sizes smaller than the tap size for the hole. If you are lucky, and the bolt is not bottomed out, you will be able to get some penetrating oil "behind" it in the hole after you drill through.
Once you get close to the tap size for the hole, the square, fluted easy-out should work after a few days of letting the penetrating oil work.
Last effort that always works. Drill the bolt out to the correct tap size, and retap the hole.
The key here is to get the first hole centered...........
ps. left hand drills often will remove broken bolts if you have them. I bought a set just for such emergencies......
