Telkom *****ing data

25 November 2020 I toped up 10GB data on my 40+40 LTE contract and the data was finished within 4 hours and i was not even at home. I checked all connected devices and nothing reported high usage or explained the issue. I called in to ask for help, a rude customer represented refused to log a fault and stated that they cannot log tickets for high usage. I explained that 40GBs lasted 25 days so it's reasonable to expect 10GBs to last at least a week, and I explained that all devices do not show that usage. All I get is an email with BS numbers "proving" the usage. Nothing I can do but buy another bundle. I reset the router, changed my WiFi password to be safe, and carried on with life. On the 24th of this month I toped up 20GB and 14GBs are already gone, again I've checked all devices and nothing shows that usage. I called in to report again, first the agent tells me that I used 600MB between the 28th and 29th, then when the numbers are nowhere close to 14GB, he says his page has refreshed and I actually used 6GBs in one day, again, none of my devices are reporting anywhere close to this. When I look into my history, November's usage dropped from a reported 130GB+ to 90GB, but of course I was never given the data back. No one is willing to help, make suggestions how to change this, or give advice / look into the situation, when I get worked up, the agent just hangs up on me. Don't join Telkom for anything, they have a reporting error and can't track it, it costs the client money, and they won't even look into the fault.
