Vodacom’s Code of Conduct - just for the website, not for its staff...

Vodacom’s Code of Conduct (https://www.vodacom.co.za/vodacom/terms/code-of-conduct) promises to resolve complaint within 14 days. But that is on paper only....

My overbilling complaint has been with them (a lady called Nosipho) now since November, and the response I get is that my complaint is justified, but "I am still in communication with the Account Manager regarding the query and he has asked someone to assist with the App as requested". I also have two other complaints which were dragged on for ages and never resolved. How does one get out of such a situation?
