Vodacom does it again

Yesterday, 19 Dec 2017, Vodacom cut my phone as they claim that I owe them R23 727.00 of which R18 000 odd is for data. I have been a loyal Vodacom client and am on the premium package for R2000 a month with unlimited calls and 5G data per month. There was no extra usage on my side. This happened to me last year as well over the Xmas period when Vodacom charged me R16 000 for apparent data usage. I contacted the The Complaints Commision and the fees were reversed. I feel such anger towards Vodacom as they leave their clients without communication over the Xmas period. This is truly appalling!
