Well it was worth a try. If it was SAE, english, fractional, inch, then you would really have a hard time getting it out unless when they put the wrong bolt in they also retapped it.
If all else fails drill it out.
But before that, get a propane torch and heat it up, although I don't like the area in which you are doing it in, plastic melts.
Take a dremel and a cut off wheel and cut a screwdriver slot.
