Should I be looking for another job at this point?

I applied for Toco bell a a little over two weeks ago. Went to the interview, and got the job. Just have to wait on hr to do their part then I can start. Thing is, my manager said it could be a week or two before I start. I just though okay cool. It's been a little over two weeks now. I texted my manager when two weeks hit because he told me to if i hadn't heard anything. A couple days later and nothing. I talked to my case manager and she said to just call him, and to explain. He said he was sick in the hospital, and he just got out. He told me to text him my full name and he'll see what's going on with hr. The son of one of my moms friends got a job thier too, and he was going through the same thing I am, so I just ditched taco bell and got a different job. Just wondering if I should do the same at this point.
