Disgusting Service At Engen Cape Gate

Extremely disappointed ☹️ at the service received at the Engen at Cape Gate. After telling the petrol attendant twice R200 he puts in R400 he insists I said R400 when I said clearly for my wife who was sitting behind me to hear. I ended up waiting 20mins to get this issue resolved while my wife and my 2month old baby is sitting in the car @18:20. When I asked for a manager I was told their wasn’t one available. An the guys kept on ignoring my request to pay what I asked for. Screaming in front of the other customers I said R400. I don’t have time to cheat people out of there money but if I ask for something and you do something different how does that become my responsibility. I got a call from the garage today and again no customer services what so ever. Didn’t ask my side of the story just jumped straight into it, we checked the cameras and he confirm with you the amount of R400.
