Most pathetic service from Centurion Highveld post office.

Most pathetic service ever. I ordered a couple of stuff from wish and every time that I need to fetch it from Centurion Highveld Post office, I receive no service at all and wait more than an half an hour every time. They go to the back to get the parcel and start talking to the other staff and blatantly taking their time. Someone needs to address this as this service is pathetic.
