Telkom

Never have I heard a load of nonsense like I did today. I received messages from Telkom that says my data has depleted whilst I was not using my phone, no internet, no whatsapp nothing, no app upgrading or background refresher on absolutely nothing. I call to enquire spend an hour waiting for operator call gets cut, spent another half an hour before someone picks up the phone only to be told that my data can't be refunded as on their system it shows I was on the internet...I ask them to givd me the times and sights and apparently doesn't show on the system. I obviously checked everything before making the call, I'm not high that I would use the data then call to say my data just disappeared. This is totally unacceptable and what guarantee do I have that If I buy more data it won't just disappear also only to be told that it happens ???
