payment of salaries to contract workers

My husband was contracted to this company to deliver medication parcels from Clicks Pharmacy Soshanguve Crossing with own car. He has been struggling to get his salary since last month and he is using our car. They are manipulative because they have a contract with Clicks, which pays them, whilst they do not want to pay people who are being contracted to them. This is a worst company to work for. our car's kilos are so high, but payment, DOLOLO!!!! Watch out for this company! They abuse people. They change delivery drivers like underwear!
