Worst in-service training for Foschini graduates

We were given an opportunity to complete an 18months service training at Foschini.we have been working good closely to 1year 1month,while others finished their contract March 2016 while others had to finish September 2016,as we didn't get paid April they tell us they are still investigating the matter,now it's close to two weeks and the matter is being investigated and at the same time we haven't got paid for April,but they are aware that they are students who signed contracts with them, we also need the 18months in-service training to graduate but the treatment we got from them was unfair as we were told to stay home even today they are still investigating the matter.lebogang hr consultant insando tfg,should respond to the matter has she knows very well we have proof the the contracts we have signed with her.
