Sounds like you could have a big problem.

You need to find a way to pull outward on the bolt as you try to unscrew it.

 

Go get an extractor. All you gotta do is driill into the broken bolt and insert the extractor, I use them alot at work. Just make sure that you use the right drill bitt. Good luck.

 

iv'e tried ez-out's fluted and spirals no luck
