Data disappearing once more

Good day<br> Yesterday I had a problem where I bought data but it was never transferred to me. Instead your system deducted the data fees and quickly depleted my airtime. After being on the phone with a consultant for about 20 minutes, the matter was resolved and I was refunded. I then bought 1G of data and was very careful with my spend. I have turned off \cellular data\" on most apps- only about 7 apps are switched on. Even last night when I slept, the entire cellular data was off. I used the Internet for about 30 minutes today- no downloads or videos.To my unpleasant surprise, my data just got finished!!! Can I pleaaase be refunded, this is just not on!"
