Dissapointed

I'm soo dissapointed I went to Pick n Pay Campus Square to buy few things I took Danone Nutriday as I got a promotion pamphlet through my whatsapp as I subscribed it says ASSORTED 900G so to find I took Plain&Mixed berries when I got to the tills it does not want to do the promotional price of 2 for R56.00 and their all priced 2 for R56.00 but by the tills it was saying something different as the cashier kept on explain that only Full Cream but I said to her it says assorted and prices are everywhere inside the fridge that it's not fair then I went to Hot counter to buy Fish hey when I got to work it was sooo hot I couldn't eat it as I'm suffering from peptic Ulcer soo can I have fish with fish spice clearly it's bad day for me and the Danone promotion can it be fixed as it says ASSORTED Not strictly FULL CREAM and the Pies there was no promotional price as it says 2 for R50..
