Hmm. I switch my South African cellphone on once a week or so to check for any sms or voicemail. I can usually count on a few messages telling me my number has won a competition, been chosen for a special award, or some other nonsense. All I have to do is call a number and speak with Mr XYZ to claim my prize...
Reckon I've won about ZAR 1.5 million (£90,000) since Christmas!
