Work and no pay

A group of us ladies were hired to do promotional work on the 2nd December 2022. We did our hours and left. We were promised payment that day and then the day after and then the following week. We are still currently waiting for payment. The lady whom hired us has chopped and changed her story. At first it was that the Client hadn't made payment and then very quickly changed to her bank freezing her account. We have also watched her go on vacation, rage and live her best life during this time. This is not right.
