Help! In first contract and no housing as promised. No $$. Advice?

I won't go into the name of the agency as I am still under contract even though they have not delivered what they promised.
I am new to travel nursing and hadn't really considered it til recently, after having a hard time finding local work in my specialty.
Saw an ad for a position about 150miles away from home that fit my skill set so I called the company and they were supernice, said that they'd put me into their housing no problem, and starting a very urgent hiring process. When I had read and signed what they sent (nothing about housing written at all) they started saying that from the beginning I'd stated that I would take care of housing. They are willing to admit that this is not really possible in most cases when the RN has 1 week from applying job to starting it. They also stated that the area was too rural and that they couldn't accomodate me, unless I lived in a hotel 80 miles away. My car is 15 yrs old. No. We settled on an agreement that they would pay for one week at a cheapo hotel while I looked for accomodations. They said that they could just keep me at that hotel until I got my 1st pay and deduct it from my weekly pay, since I don't have the $$ to start putting down deposits. Either way we agreed that I would tell them what to book for me at the hotel and they would do it, taking the $ from mypay as needed. It is day 4. I am finished with my 12hr shifts and have one night off. They are making me leave the hotel every morning and then putting me back in later. They'll only book 1 night at a time, but with a night job you sleep through the day and need more than one night reservation.
I am tired, and confused. I don't really have a full understanding of my rights as a newbie and obviously can't trust my recruiter. Oh, the reason they made me leave for today was that they haven't rec'd the results from my drug test yet. Tough ****!! You just ordered it the day before I left.
HHHEEELLLPPP!!!!! Don't want to leave contract but not thrilled about being homeless. I can't spend my last $$ on a room if I can't trust them.... who knows if I'll get paid?
