Why don't recruiters call like they say they will?

I got turned down at Aerotek for a position which is a staffing company. So I accepted a call center position with Safelite. On my first day of training I got a call from an Aerotek recruiter telling me that his peer referred me to him for an entry level HR position at Nationwide and said I was a great fit. I was excited to hear about that because it’s more pay, closer to home, a job I want and full time.

He told me that I just need to take a customer service test and listening test. He said that the position starts ASAP which is within two weeks and is a 6 month contract with potential hire. No interview involved since I interviewed with the staffing agency.

He sent me the tests which I took and I scored a 95% and an 85% (on the listening) I don’t know if that 85% is passing or good enough. But in the email he said it looks good and “I’ll call you tomorrow!” but yesterday was tomorrow and he still hasn’t called me today. I called him yesterday and left a message but still no response.

I’m worried the position went to someone else or maybe they didn’t want me. Why do you think he didn’t call on the day like he said he would or return my call? Is that a bad sign? =\
