Worst Service provider in SA

I need Vodacom to explain to me how after the 4th time phoning to follow up on the progress of my sim swop to Telkom, it still hasn't even been logged never mind processed. Excuses like system being down, power failures, etc are not good enough. It is more like incompetence and lack of quality customer service. The exact reason why I am no longer wanting to be a customer of Vodacom.
