Brand Ambassador shifts results in no payment

My name is Jacky and I was working for The Creative Counsil (TCC) on an activation/promotion for Cheas Naks that took place on the 26 and 27 May 2018 at PnP family, Oakdene. On both days I had made sure my proof was sent to confirm I was working (which was a picture of myself as well as my stand). It has been a month and after several attempts to enquire about my wage payment I still have not been paid, higher management has not been able to resolve a simple matter that is clearly TCC 's negligence. Till this day I have not been paid and there is no progress on my case. For a first time experience working for this company my experience thus far has been nothing but unpleasant, and do not wish anybody to go through what I have.
