what would you do ? A potential job still hasn’t gotten back to me

I applied to be a kennel assistant for a veterinary office, and they called me in for an interview. It went great and the guy said he would call me the week after to start training. He never called me, so I called him myself. He answered and said he had to fill out paperwork and would get back to me, but that was two days ago and I haven’t heard anything since..so should I call again ? Or is that annoying and I should just look for another job ?
