Yes, I too fell for their horrible "marketing campaign" (data harvesting) exercise on WhatsApp. It was so poorly thought out and difficult to to use (what was wrong with a form?!), and the only reason I can think of that they let it run after all packs had been (allegedly) claimed was to harvest data. If you were a victim of this too, make sure to email to get your data removed so they can't sell it. Never going to buy their drinks again.
