Poor Service

Almost 3 months ago I received a call from Dstv offering me Dstv explore, the sales person said I'll pay 49 rand extra for 24 months it's locked then someone will come and exchange the dish and the decoder l. A month passed I gave Dstv a call to find out what's happening I was told they will escalate to the team leader waited a month again for feedback I called to find out what's happening same story will escalate to the team leader. Last Friday I called to find out then I'm now told the special is no longer running I'll have to get someone to install the dish and decocoer myself, I asked what other options do I have I was told I'll have to pay R150 extra because that special is no longer running why did I wait 2 months to do follow ups then I told them they should check how many have I called for the same problem and I don't understand how is it my problem now yet you're the one who initiated this offer and now I'm sitting with a decoder here which is supposed to be picked up and hasn't been picked up. Dstv you should stop selling us dreams I'm really not happy at all.
