PostNet Courier Sandton City Poor Service

I'm extremely disappointed with the appealing service I received at PostNet Sandton City. It is not enough that they were staring at me while I waited to be attended to while they had a gossip session, but when they finally felt like attending to me they completely uncourteous and showed no care. They didn't greet nor show concern that a client had been standing there for 10 minutes while they were loitering in the shop. The employee that assisted me didn't even greet but asked rudely "what do you want to be helped with" after having to demand assistance. They didn't even care to tell me my charge for the service they simply just pointed the speed point at me to tap and pay. I've had a great experience with PostNet each and every time I used their services at Northmead and Pretoria CBD.. but Sandton.. I will never set foot there after this terrible experience
