Lack of customer service

My M-Net Analogue service has deteriorated over the last two weeks to such an extent that one could not watch anymore. I called the call centre, third time lucky someone answered and after a long explanation and waiting period I was informed that the transmission from the transmitter is degraded. Waited another day and the service was even worse. Called the call centre again and spoke to two different agents, each giving me a different story. I eventually suspected a decoder fault and returned this to the N1 City branch (2015/07/29). After a long and frustrating experience I was given a replacement decoder. This however cannot be enabled as the customer staff do not have access to the system and only one person (Luyanda) within the organization, stationed at the Randburg branch, can do this. The problem, I have been told, is he does not answer his phone, or read his mail. I requested a contact number to escalate this, however I was informed there is no one!! I was told to await their call. To date, I have heard nothing again. In a nutshell, this is s****ing the proverbial bottom of the barrel when it comes to customer service!! Who cares attitude by all that were dealt with.
