Bad Service

I have been contacting the call center since Tuesday regarding my paid up letter for telkom mobile, however no one is willing to assist me, I then called again today to check up on the progress they keep on telling me it is still on progress, and what annoys me is that no one is willing to help me. and I really need the letter as I need to send it to trans-union. I Spoke to Nthekhi tsupugsetsu the Agent and I spoke to sibusiso map****lo claiming to be the floor manager, and all of a sudden he tells me about 48hrs knowing very well I have been calling from Tuesday.. What more do they want as i have waited more that 72hrs? I mean its clear that his agent are the one who is not doing the Job.. what is so difficult on sending paid up letter? telkom sucks and the agents are full of **** they do not know what they are doing .
