*****ing my airtime!!!

So I had just under R50 of airtime before i went to sleep, I woke up this morning and decided to buy more data. Checked my balance had about R43 and then i try too purchase 100mb for R19. Firstly, at the conclusion of my purchase i get an sms telling me that my tariff change has been unsuccessful and that i need to recharge and try again. <br> <br> That surprises me and i check my airtime balance i now have R17 so am not amused. call the call center tell the lady my problem then she tells me i have been using the internet since 4am and that's were my airtime went. I explain i was not online and then she tells me about apps updating and so on. now<br> 1. all my auto updates are disabled, nothing updates unless its on wifi and i choose to update.<br> 2. I lost approximately R19, amount i was trying to buy data with.Coincidence?<br> 3. 2 emails came into my inbox, and i didnt open them. Now by your consultant's reasoning those emails used about 20mb of data. I find that very hard to believe.<br> 4. What is this stuff i get about tariff changes. I didn't try to change my tariff!!<br> 5. Since then I have ben unable to buy data so guess what have to use my airtime.<br> <br> Once this airtime is finished I am done Cell C.
