Poor customer service

Last week I posted a report regarding the service i received from Cell C, then I was contacted by Nelly Mamotheti. She promised to investigate the matter and give me a feed back but she never did even today i haven't heard a word from her. I then called back on Friday 15/04/2016 and I spoke to Kgomotso Motsepe who told me that there is no case open on my name the only case she saw was closed, i asked her why and how was it closed she refused to give me any information. I asked if I can speak with her supervisor then she put me on hold for a very long time that i had to drop the call. I need someone to give me feedback no later than today if not then i'll have to escalate this to the ombudsman.
