NO ASSISTANCE FROM VODACOM

I have been trying to get assistance regarding an unknown number being billed on my name since December 2017. After submitting all the documentation requested by Vodacom I received a mail saying that I will have feedback within 7-14 days. It is now two months later, no feedback what so ever! I posted a complaint on 25/01/2018 and received a response that someone will contact me. No one contacted me yet! I make numerous calls a day trying to get someone to assist, but I get transferred from one person to another! This is Pathetic!
