NEDBANK DECEPTIVE ADVERTISING

I came accross a Nedbank campaign where they promised you 1Gig of data and a R500 Edgars voucher if you open their Pay as you Use account online and swipe their card. I opened the account online and only received 1Gig of data, when I followed up to enquire about the Edgards voucher, I got sent from PILLAR TO POST until now. My complaint ref was ***4. THATS DECEPTIVE ADVERTISING.
