Where has all the data gone?

<p dir="auto" style="color: #000000; font-family: sans-serif; font-size: medium;">Hello, my name is Michael du Preez<br />I am a computer and phone technician with may year of experience dealing with data and airtime issues attributed to badly setup app and phone settings. However, in the past few months, I too have been experiencing the sudden leakage of data and airtime. Just today I had R11+- airtime, made a 30 second call and was left with R4. I have had multiple occasions of my airtime being used instead of data and data being used up, despite strong fail safes to protect it from data hogging apps. But non of these symptoms are constant. One week all is well, then the next, I spend R500 on airtime, yet only call for a few minutes. This has got to stop. Someone needs to be held accountable.</p> <p dir="auto" style="color: #000000; font-family: sans-serif; font-size: medium;">Mike</p>
