MTN running promotions where nobody knows how it works.

MTN is currently running a promotion on their Samsung A80 phones if you upgrade or take out a new contract you get a Takealot voucher to the value of R750-00 great you might think. Until you realise no one knows what is the hoops you have to jump through to claim it. Yes you understand me correct you have 14 days to claim the voucher but nobody knows how do you go about to claim it, not instore neither on the MTN direct line?, False advertising?
