Vodacom Fibre not responding to fault reports

On Monday the 4th of November I logged a fibre fault telephonically, no joy, then logged a fault via email, subsequently have made about 4 calls and logged another 3 times via email. To this day, no one from Vodacom has attempted to assist me. My business is suffering as a result and Vodacom just doesnt care. What do I have to do to get any response???? Honestly, this is the worst service I have experienced.
