Advertising deception

I ordered 3 x Kit-Kat Mcflurry's from the Mr Delivery app on Saturday and from the picture on the menu it looked great and worth the R56.00 they charge per cup. The picture on the menu showed an overflown plastic/glass container with ice-cream and a whole lot of sprinkle on top. When the order was delivered to me, I was disappointed to see that they gave me 3 half full paper containers with ice cream and a bit of what looks like chocolate sauce on the top but no sprinkle. I asked them to return the product as it is customer advertising deception and I got rudely interrupted by the lady working at the branch where the items was ordered from who told me that I got what I ordered and they will not take it back. I then launced a complaint with Mr Delivery and was also informed via WhatsApp that I got what I ordered. On Monday I launched a complaint with McDonalds self and has since not heard anything from them. Their Ice-Cream is still in my fridge awaiting upliftment. I cant see how anyone could pay R207.00 for 3 half full cups of ice-cream that doesn't even look the same as the once advertised on the menu. McDonald's, I am awaiting your reply please.
