apaulling customer service and empty promises

My husband and I had a disagreement with a dstv agent yesterday at sunnypark pretoria about a dstv package purchased by my husband in 2011,he never recieved his dish and disnt need it at the time,he was told by the agent who helped him that whenever he needs it he can just produce the copy of the contract he has and he will get his dish,he has moved from where he previously lived where there was a communal dish..and we now need it,we were told theres no such,this can never happen. We finally reached an agreement where we bought a new dish and were promised free installation the next day,the day is almost over and we have recieved no calls,texts or emails from these people,when we called the stand earlier we were told that they would be unable to help us because they dont know where the installers are at that moment and calling them was not even an option. We finally managed to hear from the installers who eventually hung up on us when we tried to contact them again. We are still here waiting for these people.
