False Advertising?

President Hyper in Krugersdorp used to be the cheapest in the area but NOT ANYMORE. They do false advertising and their service sucks! On the 4 September they advertised Creamline salted butter for 49.99 per 500g. I visited the shop on that day but there was no Creamline butter on the shelves. I gave it two days and went there again. Still no butter! I went to complain at Customer service who informed the were sold out...no stock! This was a lie! they never received or unpacked such butter. They gave me a "voucher" that states I can have 4X500g bricks when they ever receive such butter again! I am still waiting for there call! Personally I will boycott them. Like most super markets is this country they have slipped into 3rd world state! Shame on them.
