Real Staffing interview questions

Was contacted by 2 different Real staffing recruiters for a 12 month position they had with their client. The first one called me multiple times on the same day and I submitted my resume and other information he needed on the same day. However, he never got back to me after that, stopped responding to my emails and calls too. Had similar experience with another Real staffing recruiter around 1 month back too. Totally unprofessional to contact jobseekers, ask them for resumes and other relevant details and then with after giving no update, stop all communication with jobseekers !
