What should I do?

Hello everyone, This is my first post and I was hoping to gain some great advice on what to do in my situation. I recently started looking for a new job after my most current job was not what I was looking for. I applied to a new facility. Luckily I got a call to come in for an interview but missed the call. I called back and ended up playing phone tag for 1 month with the unit manager. When I got her on the phone finally she scheduled my interview. Awesome, right? Not exactly. When I went for my interview another lady did the interview and offered me a job on the spot. I informed her that I had to give my current job a 2 week notice. She said that was fine. Now here's my problem. I'm done with my 2 week notice and now I cannot get anyone on the phone or to call me back to schedule my orientation. I keep getting short answers and I'm 2 weeks now out of a job with no paycheck. I feel like I'm bothering the new employer but it's starting to make me mad that they are dragging their feet! I need a paycheck. What should I do? Look for another job? No one will even call me back and I've been trying constantly. Any advice would be great. Thanks!
