Hi all.

I'm looking for anyone who may have worked, or knows someone who has worked for GnB in Indeogwon (Anyang) or Migeum (Bundang).

Basically, the director Cristal is giving me cause for concern.
The full story is here: http://www.ddongjip.com/blog/?itemid=83
To cut a long story short, she hired me, we both signed the contract, I got the visa and then she "cancelled" the contract the day before I was due to fly to Korea, saying she had hired someone else.
I'm now in the situation where she has my degree certificate, a visa I can't get out of unless she cancels it, and she owes me a couple of hundred (us dollars) for expenses.
I have asked her to cancel the visa and send my degree back to the recruiter, but I have had no reply from her in over a week.
I am becoming increasingly concerned that she may be either deliberately trying to screw me over, or she just doesn't care how much trouble she is causing me, although I can't imagine why.
I have also found another post in a forum, posted by a korean teacher who used to work for Cristal. She was furious, saying that Cristal treated her extremely badly, didn't pay her, and then fired her without notice.
I am trying to decide what to do. Do I give her more time or should I maybe complain to immigration and ask my Korean friends to contact the police about getting my degree back?
Does anyone know this director?
