Invoice Correction Nightmare

<p>Since the 29 December I have been battling wiht Vodacom to solve a simple situation. There was ***** done on my aco**** and after following all their steps, it was finally declared a ***** case and I could finally upgrade. Vodacom, however, decided, I would still be billed for this device they declared was loaded via *****. I called them on the 29th December and got a reference number. I kept calling and after service requests to one manager to the next that provided information that had nothing to do with what I requested (someone within vodacom wrote in the Service request I wanted to cancel the contract, the other stated I wanted to switch to prepaid) none of which I actually requested. So, here I am, a day before another deducted, still incorrectly billed having spoken to about 15 people including a Funeka, a Kgomotso at solutions, emails sent to HoDs at the back and still nothing. So, what does one have to do in order to hold vodacom accountable short of seeking legal action- which is what I have decided will be my next step</p>
