Prices on shelf not matching correctly

I've been to makro amanzimtoti so many times to buy something and the price does not match what it is online or advertised. I get given the excuse of the website and instore prices are always different. The makro website does have online specials yes but not all stock online and instore are drastically out. I always go online to compare prices to other stores. Needed a cable the website says is 89 in the branch and it not an online special but when I get to the branch it is 149. The people you have working there either ignore you or pass the buck. Makro amanzimtoti has gone down hill and does not stock as much as Springfield branch. They keep 2 flavours of monster. Every time I want the sugar free ones I must drive to Springfield where they have 6 different flavours. Makro amanzimtoti must jack themselves up.
