No delivery of TV set as per contract signed 29/12

i took an upgrade on my phone contract on 29 December 2014 at MTN Store at the Design Square in Brooklyn, Pretoria. The upgrade phone I chose came with a television set. The attendant - total lack of customer focus or interest in helping or answering queries in all staff - told us we would be called for the delivery of the TV in about two weeks. There has been no call, no explanations about the delays or when we should expect it or what was causing the delay. In fact, when we go to enquire at the store the staff seems irritated and totally uninterested in resolving the issue. Or maybe just giving hope and being apologetic for this breach of contract. Last time we went they gave us a number to call and enquire: ***. Not even once is this phone ever picked up. We went on Twitter. An apology came swiftly and we were given @MTNzaService to submit our query (REQ: ***). I have submitted and resubmitted - NO RESPONSE. Going back into that store in Brooklyn and subjecting oneself to the horrific attitude of the staff there is an option I would choose very reluctantly. It's a very unpleasant experience. Does MTN still exist in South Africa? Are they capable of resolving this?
