Uncertified customer and incompetency of the staff

I have received the worst service from the multichoice call center customer service. I went to the Benoni Multichoice outlet due to a decoder had drive malfunction. The lady (Bettie) that assisted me was very helpful. It only became a problem when we called the contact center and spoke to Gavin to fix my insurance start date. I was told my query has been escalated and I should wait 20 minutes. I waited and nothing was done. I called again and next person that helped went an extra mile by walking to the department were the problem was supposed to be fixed. This happened after I fought and refused to wait another 20 minutes. I was able to get assistance. When I got home my decoder was not working. I called the call center and spoke to Asavela, she said she will escalate. I called again and another person, and they told me the same thing. I called for the 4th time and spoke to Bulelwa who told me the same thing. I hate the service that was provided to me as it seems that the people are ***********. Even the management is not available. TNo one is willing to help but they are quick to debit a person's account.
