Am I entitled to pay if I quit a new job after 3 days?

So I started a new job Wednesday last week, got to the end of the week and decided it wasn’t the right fit for me.

Sent in my resignation Saturday morning via email outlining a few personal and professional reasons why I didn’t want to stay with the company. Got a reply asking for more feedback, replied to that and never got another response back but my online HR account listed my employment commencing on the 11/01 and terminated 13/01.

I worked 3 full days, longer hours than anyone else on my team because I really wanted to give it a chance.

They process pays on Fridays so I’m assuming payslips go out Thursday but there’s nothing in the HR Portal.

Am I entitled to payment for those days? From what I’ve read on the fair work website final payment should be made within 7 days of the end of my employment (tomorrow).

If I’m entitled to this pay do I have a case to take to Fair Work if they try to avoid paying me?

Thanks in advance and sorry for any formatting issues, I’m on mobile.
