Irrated pregnant woman who has to deal with a Rea vaya employee that insults us

I'm a very frastrated pregnant woman who has to deal with a VERY RUDE employee hired by Rea vaya I'm super angry sick and tired of that man, he fights with every one at the station his attitude is the worst when you want load the tag the system is always offline but when his not at the station the system works very well and everyone is happy with no insults he doesn't even have a name tag when I ask him for his name he says he is the supervisor. His based at Parktown station.. Please attend to this matter before you start losing customers over a stupid employee
