ONE MONTH AND STILL NO FEEDBACK!!!

I Reported this case with customer care on the 24th of FEB 2016 with the Ref number ***5 and didn't receive any feedback. So I reported it on hello Peter last week Monday on the 14th of March with the case number sm212630. It has been a month now without any feedback. I had this same contract of mine since August 2013 till now. I can't upgrade because telkom mobile said I can upgrade October 2016 because I had my contract since October 2014. I've sent the proof to them but nothing is happening! I am still paying for the same blackberry! That is *****ing! Is it my legal right to take telkom mobile to court because I'm not getting any answers and I have all the proof! If this is how you handle your customers then im putting this on all the social media that I can think off! Point is how can I still be paying for a cellphone that is already paid off! Telkom mobile is a rip-off!
