Vodacom contracts department, misleading and incorrect billing, no response from customer service agents.

I am having endless difficulties with my vodacom cell phone contract for almost a year,I am being incorrectly billed and my monthly premiums have being adjusted without any notification being sent out to me, the vodacom customer service agents that I am dealing with are blatantly ignoring my emails now and my account has been suspended.

This was after I was mislead into signing up for a migration by an agent on behalf of vodacom, vodacom conducted an investigation into the alleged misleading and confirmed that I was mislead by the agent, however the ongoing issues continue to persist.

I cannot seem to get in contact with any senior management of vodacom dispite me requesting for my matter to be escalated , can someone please assist me.
