Bad attitude at Telkom, Vincent, East London

I have requested a upgrade, relocation and installation of new adsl line at the 15th of July 2018 from Telkom. We are already sitting at the end of August with no solution given. I have received an sms 3 times stating that they will be there the next day to install the line, waiting in vain...no-one arrive. Today (20 August 2018) I went to telkom in Vincent, East London to see if I can somehow manage to get an answer. Being served by BOBBY CHWEBI, I have never been so humiliated in my life in front of other clients, in public. Not only is it embarrassing but it is also very degrading. Is this what the Telkom brand stands for?? He was extremely rude and made fun of my enquires by asking other clients what they think of what im asking and then laughing about it. Customer service is very important in any retail business. If this is the way that Telkom treats their clients, then I am quite amazed. I have been paying my account on time even though I don't have any internet provided at the moment. I have been very patient with the installation of the new line. He couldn't give me any answers as to what I'm asking. In the 2 years I have been with telkom have I never received service from any employee that was as rude as this time even if their service is not great, don't treat your clients disrespectful.
