Should I call back a place that said i'd be a good fit?

Hi :) I recently applied somewhere about a week ago and was told i'd receive a call on Sunday, I have unfortunately yet to receive a call which leads me to the question, should I call them just to ask? I was told the call would be if I got the job or not (and since I didn't receive anything, im just gonna assume I have no job) but most everyone ive spoken to has said just to call them again to either confirm or deny my hiring process. What should I do?
