OK, recently there's been qite a few posts by people saying
"Oh no, i withdrew some points but they're not in my pocket or in my bank! What's wrong?"
When you withdraw some points it takes a while to update, sometimes UP TO A FEW MINUTES.
So before you post your 'I've lost my points' thread, check again, you may be lucky!
EDIT: Either that or someone nicked them from u!! (Thanks Seredith)
Hope this helps and saves some posts lol
