Telkom case still pending from 4th August - Now (27th Dec)

When the first Telkom System Failure occurred back in August, I had sent airtime from one sim to another because of different Mo'Nice options, I then got a on screen notification saying my request is being processed and upon checking my balance the airtime was deducted but nothing was received, I tried again sending more airtime and again the same thing, I called the call centre and the telkom agent said there system are experience technical failures and she does see that the airtime was deducted but never received on the other sim, she then opened a case on the 4th August, after calling about 20 times in 2 weeks about my case they said the same thing that I have to wait for feedback and they've escalated my case, My case was then closed within 2 months without any kind of response from Telkom or any note on their system regarding to why they've closed the case. Another Agent then opened a New Case in on the 17th of September and I haven't heard from Telkom since then.

I would like to know how to settle such a dispute.
