Not being paid from work.

I started working at this restaurant a few weeks ago, it's paid weekly and and firstly I didn't get paid, this was because I haven't been registered onto the clock in system, so I thought this was all alright! They said I needed to write down all my hours I have done and then they'll pay me the following payday, and again never get paid. I have to ring up Monday and speak to some finance woman of the restaurant, I still haven't been registered onto the clock in system, it's poorly run and managed and im on minimum wage but I need this job.

Im thinking maybe I have put the wrong bank details when I first started? If this is the situation what would be likely to happen? Will I ever get paid if so?
