2 months and 10 days without feedback and *****ing

This is now my 3rd complaint about the same problem! There is no feedback and customer care doesn't care about the problem. Each time I ask to talk to the manager or supervisor they are not available. I've opened my case on the 24th of Feb and still waiting for any feedback! Now each week I call customer care to find out if there is any news they tell me they will send a email and so it goes on. Now today I called again just to find out they closed my case because I the can't reach me( #******** story!) they are *****ing my money and I was sepposed to upgrade last year October! But I can't upgrade because there is a problem on telkom mobile's side that say I can only upgrade in October 2016. And how can I still pay for a phone that I took august 2013?! I will take telkom to court and I wil sue them! I'm finished with telkom! I already stopped my debit order. The are in breach of a 2 year contract! Take my advise and never go to telkom mobile!
