Alcatel robs students of payment

We were offered promotional work for Alcatel one touch. We were to work from Friday 26sept 2014 to 28 sept 2014 in mtn stores throughout Durban(KZN), promoting a cell phone. A number of worked. We were promised R80 an hour and worked days from 10am to 2pm everyday. This totalled up to R960. To this day 10/03/2015 none of us have been paid. The company insists they have paid us but no physical payment had made into our accounts. After much effort, I have had little Cooperation from Alcatel and no success in my efforts.
