Vodacom is *****ing our data and i have proof.

We've been having numerous data issues with a number of sim cards for a couple of months now & we decided to investigate matter thoroughly by isolating one sim card. We loaded fresh data bundles on the 27 August and I was shocked to discover that the data was depleted by the 8 September, I called Vodacom Customer care immediately to request itemized billing and to log a query but I were advised to visit a voda shop. <br> <br> On 9 Sept I received a call from Candice Major, Damn What a waste of a phone call and my time. She told us that our data was consumed by whatsapp and the internet but i told her that is IMPOSSIBLE because that sim card is inside an industrial modem which can't be used for anything else except sending information to our cloud servers and we have entire data transmitting logs for the period in question. she gave(Bribe) me free 2gb data bundles to try to make the problem go away but I wanted answers. <br> <br> Later that day, I visited vodacare @ Vodaworld to try to get access to itemized billing but i was told it can only be accessed via vodacom website and the query was escalated to Fabian Isaacs. To this date, No one returned our calls and we haven't received itemized bill
