False advert, ill-informed staff

Over the weekend I was going through the #pikfest game catalog and saw game advertising 2 PlayStation 4 or 2 Xbox one games for R500. I thought this is a good deal and decided to go buy two games. First I went to Eastgate where I was told that only the games that are visible in the catalog are part of this promotion. Now there were 5 ps4 games and 1 xbox game in that picture... I thought that's strange and left without a purchase.

A friend of mine then said he got two games at a Capetown branch for R500 so I went during my lunch now to the Rosebank branch where Gerald helped me, he first went to confirm the games I wanted, he came back and said all is well, I went to the till to pay and was let down yet again and being told the games I want are not part of the promotion.

I'm now very frustrated and confused. There is obviously a mistake in the advert as it does not mention that the promotion is only on "selected titles only" and also the staff is then very ill-informed.
