Bad management

Sent my CV and got called same day for an interview (Tuesday) and asked me to come back on Friday (followup interview),cool they hired me and started working straight away. It was woman's month and it was packed I worked until Sunday and they told me to come back Next week saturday.on Saturday I went and the manager said who called you??!!! I was confused and the management said no1 called you and I took my bags and left, until now they ddnt call or pay me for that weekend that I worked.... Very rude management especially the main manager!!
