Nesquik Powder Milkshake

I called Makro to find out if the special is still on of the Nesquik. 3 x 500g for R80 and they said yes. I then went to the store only to find out they don't have any strawberry flavour in stock but they never said that they only had chocolate flavour. Extremely upset I was. There was then only 1 x 6pk 250g strawberry on the shelf of which was R128 but they brought it down only R9 of which I then paid R119... Still not a special. For the 3x500g=R80. (Special) of which I paid 6x250g=R119 ( the quantity is exactly the same). I then paid an additional R39 of which I find unfair.. Why not give the 6pack for R80 as the quantity is exactly the same and the only pack left. Firstly they don't communicate correctly to say there only one flavour I store, I wasted my petrol to drive to there and paid additional for the nesquik ... I am really upset..
