Stay away from Vodacom, they simply don't care!

As of end Aug my account was up to date. Throughout September I monitored my account via the My Vodacom app to ensure that I didn't exceed my data availability. I have a screen shot saved of my outstanding balance according to My Vodacom app taken end Sept reflecting the outstanding balance which was the correct amount and the amount that I paid. Then I suddenly get notifed by Vodacom that I owe an additional R3 400, which made no sense whatsoever and i immediately asked them to investigate which they agreed to do. This was on the 1st of October. <br> <br> After some time of receiving zero feedback and voice recordings to pay the outstanding R3 400 I called Vodacom and was told to ignore the messages because they're automated which I did. Then I sent a follow up email about a week later to Vodacom via their website complaining about lack of feedback. This was never responded too. And today, more than a month later, after receiving zero feedback, my lines get locked. Vodacom informed me that they can't unlock it until the investigation is complete even though I've informed them that its an error. They have no concrete feedback and yet still proceed to shut down my business!
