Being nukes we might want precision in our answers. If you had a written contract to work for a certain period of time, you have recourse. You can file suit for specific performance (i.e. let you work for at least that period) or for damages (i.e. quitting job, moving, etc.) If you had a contract for at-will employment, you have the right to move there and work for one day. They can fire you for any reason in at-will employment.
These are courtesy of my Law and Economics Course in college. They are therefore "in the abstract," and I'm not a lawyer. Still, these are generally true. If they intended to hire you and then didn't, and you quit your job, then they do not have the moral high ground. Obviously, it matters what you have in writing and the laws of the states which you work in. If they "hired" you then the contract is subject to the laws of your state, since that is where the contract was made. There are things called parole evidence rules which limit the entering of evidence such as "they led me to believe..." or "we knew we were going to do this..." into a court preceding.
Of course, your only recourse appears to be to ask nicely for what you think your entitled too, then to threaten to use legal recourse, then to use legal recourse. Again, I'm not a lawyer, but I am knowledgeable and a pragmatist. Also, should you actually win a real court case, you cannot be repaid for "figuring it out." Production of legal knowledge due to any lack of understanding on your own part is not something courts will consider. There is only so much the courts allow themselves to help you with.
