faceless staff taking no responsibility

On Monday being on holiday we went to a representative of Dstv in Margate named Martin Electronics. We got a extra decoder and card as a existing customer for years. Due to upgrade in system they could not activate the extra card on existing acc on new decoder purchaded there at the store but assured me we can contact the cell on the box as dstv has a program to do that. After several calls dstv indicated they cannot do as was promised by the agent. After conversation a \Work around "proposed to temporary put on wife's name and on our return today and after several calls this could not be done. After being a loyal customer for years this not acceptable!. All representatives we spoke to were unable to take ownership and unable to assist. Some tried and others arrogant and damaged our trust in Dstv. Very disappointing. Also being faceless. No direct contact and deny to give any direct contact. Take a number???? No vallued customer. On all calls I requested to listen to the first call. Without doing that I got a defensive response. You need to do change of owner. Without listening to the tape how can you judge??? I have all names and time of calls. Call for names but mirrors of dstv"""
