Aggressive service

To whom this may concern. I went to a DHL depo today in Olympus Village Center in Pretoria, South Africa. The worst and most rudest man that assisted me. I got there with a bunch of important documents I needed scanned and emailed. The man was very rude from the start and asked me very rudely if I want all of the documents scanned to which I rep**** "yes" and then he just shook his head. He then asked if all the staples has been removed, i told him that he can double check but i did make sure that there wasn't any. He then took all the documents and kept complaining that the machine can't pick up my papers because it is sticking together and kept asking what type of paper I am using. While scanning my papers which was clearly a big irritation for him another lady came in and he started helping her. He then copied papers for her while my documents had to stay one side although I was there first. I then had to comment after he did it a few times that I was there first and this is unacceptable. He just looked at me and continued. The man then found 1 staple out of 277 papers that was copied and he was extremely rude to me about it. He spoke to me loudly infront of everyone there. I then said that I am very sorry, i clearly missed 1. Hen then slammed the paper on the desk and pulled it out. The service I received was aggressive and mean. It felt like he was doing me a favour and not that I am the customer paying. I paid almost R300 for this to be scanned and then get a **** out from your staff. This is truly unprofessional
