Info about On Assignment travel company

I was looking to switch travel companies and I decided to check out OA since I have heard so many good comments about the company, I spoke with a recruiter about the travel packages and everything sounded fine, I filled out the app, and was told to fax my paperwork over ASAP because my recruiter will be receiving her hospital needs list at the end of the week or the beginning of the following week, needless to say that has been 3weeks ago, I left a message and a email just to find out whats going on and haven't received a call back, I don't know if I should look elsewhere for another company or request a different recruiter. Any advice from anyone who has traveled with OA would be beneficial.
