Milo SA false advertising

Hallo. So at long last Milo had limited edition 500g tin plus a mug. Saw it on Pick 'n pay catalogue, went straight to the store specialy to buy them. Then they had no stock and gave me a raincheck. Well two weeks later they phone me to come pick them up. So second time I drive to Pick 'n Pay specialy to buy these mugs and Milo. Very excited about our Milo mugs, I open the boxes just to be terribly disappointed by the plastic kiddies cups inside. They look absolutely nothing like the ones advertised on the boxes cover. I now ask Milo SA do they purposely do this to deceive people, or was this somehow a mistake? I am deeply disappointed in my favorite drink... I believe this to be false advertising as I and probably hundreds of other customers though this to be prober mugs, not plasic toys... Waste of my money...
