Data contract, bad attitude from call centre agent

I'n now nearly 4 years with 8ta (telkom) and never did any agent that I spoke to inform me that I cannot load extra data to my contract !!!! This month I did need extra data so I bought 3G for R199. When I want to load it on my contract it was denied. I phoned the call centre and was told by Mongesi on 18/10/2015 @ 13.05 that his manager will phone me back so that we can discusse this problem. On 19/10/15 @ 13.24 I phoned again because NO call from the manager as I was promised by Mongesi on 18/10/2015.<br> I spoke to a lady by the name Thanysele Ngubeni on 19/10/2015 @ 13.24. She is very arrogant she even told me the time I want to write down for my call is incorrect and she said she will spell her name to me and I can go to the newspapers if I want !!!!! I explain to her my problem of yesterday (18/10/2015). She said her manager is in a meeting and no manager is available to assist me with my problem and the managers will tell me exactly what she is telling me. She was blaming me the whole time that its not the agents who ever helped me mistake that I didn't ask questions or readed my contract properly !!!!<br> Very good customer service !!!!!
