Nedbank had a promotion in June to pay clients R1000 for switching their salaries. I did that. Needless to say I have been send from pillar to post about my R1000 still today. Initially they said I would get it on the 15th after the send salary has been deposited. All the time I call in they promised to call me back but they never did.
