What should I do at this point of getting a job?

I was supposed to get a job at Subway. I turned in the application. I went in for an interview, it went well, I filled out all the paperwork, etc. I got my job permit and everything, the manager told me that everything was set, and he would give me a call when I could start working. He told me this on Monday, and he said that he would call me FOR SURE by Tuesday afternoon. It's wednesday and he still hasn't called me. Do you think I should go and talk to him, or do you think that he's not going to give me the job?What should I do at this point of getting a job?
I would ring him.

I lost out on a job once because someone had written my phone number down wrong.
