Worst Customer Service in the World goes to Telkom

We have a Telkom LTE data Line and for 2 months it was running at 10Mbps. A service provider has added one these Cellphone towers and all of a sudden we are running at 1Mbps. I have contacted the Call Centre on 082 180 and me and my wife spoke to 4 different agents with the worst attitude and is not willing to help and talking to friends while acting like they care about you. Thee agents were Smangele. Mahlongonolo and Mrs.A Zulu. Hope you never deal with them. Till today no assistance is given, no solution was given and the problem is not resolved, You can contact Telkom for feedback and then they say we are working on the problem, when you request to find out what is the problem then they tell you we don't know, so I request how do you give feedback if you don't know what the problem is, then Mahlongonolo put the phone down on me and A. Zulu told my wife she is stupid. We don't even started on the fact that they will put you on hold for 20 min and then comes back to and say what was I assist you with. I personally thing the worst company in the world is Telkom when it comes to customer service.
