disgusted at the outcome of my complaint

On the 22 April 2015 I received a call offering me an upgrade. When I asked about my existing contract I was lead to believe that its no longer available. The New offering is +/- R140 and a AG mobile phone and my 'old' one was R99. I then took the upgrade. On the 8th May 2015 I received another call, offering to renew my contract st the existing price of R99 and a new samsung. At this dtage I was very confused. The call was terminated when I advised of the other offering. I then logged a complaint on the 13 May, reference no ***.I was advised I would receive feedback within 48 hours. Never received a call. I called in again on the 18th and was once sgsin advised I would receive feedback. This also never happened. I called in yesterday and again today. The call logs were received and even though it was admitted that what I am saying is the truth, I am made to believe I am at fault.
