Rude supervisor and ******** drivers

Ordered food for R106 and I had only hundred rand notes and one R5 coin. The driver said he didn't have change and I gave him R205 expecting R99 change. He said he was quickly going to the fuel station to get change but never returned. When I laid a complain with the supervisor Ben, Ben told me the driver said "I had send him to buy ******s" and he believes the driver. He went as far as accusing me of being aggressive with the driver. Their service is pathetic, disgusting. Still waiting for apology from Ben and also waiting for his driver to return my money.
