24MB just disappeared for simple Google search..,...BS!

Bought a 350/350MB 180 day data bundle at 12:50 and did a google search and switched off my data as I always do. Literally 10 mins later I get an sms update that I have 326mb left!

HTF is that even possible. I've bought this and other packages for the past few years now and NEVER have I received an sms update this quickly or ever used that much data that quickly. I've always used a firewall to block ost of my applications from using mobile daata and have wifi access only.

So what happened to my 24MB TELKOM!??????
