Below Acceptable Customer Service

As a long time Cell C customer I am saddened that Cell C has fallen into the bad customer service trap that most South African companies has fallen into. Over a year ago Cell C granted a ********** contract to an individual on my name. And it took the longest time for them to correct. But they fail to clear that issue off their systems regarding the issue. I have been trying for over 2 months to upgrade my contract at branch level they keep telling me they get a Customer Query on my name and therefore cannot assist me. The branch and Cell C head office share the same system, but when I phone customer care they don't know what I am talking about. There is no interest on their side to resolve this and therefore my next step is to contact the Obudsman.
