Won a R5000 Voucher, but still awaiting feedback

I received a call earlier today from an 011 408 number to let me know that I'd won a R5000 voucher for use on their online store. I was told that I would receive an email to which I needed to respond with a copy of my ID and other info. He also confirmed my email address with me.<br> <br> Unfortunately I haven't received that email yet. And also didn't take the name of the person who called.<br> <br> I would appreciate it very much if someone could get back to me in this regard.<br> <br> Thanks.
