Misleading Promotional Pamphlets

Good day On the 23rd August 2018, I received a cal from my friend that there was special at Tops Newtown, when I went I saw on the promotional pamphlets that Courvoisier XO Cognac was going for R 299.99 but when I order for it they told me that it was a mistake but I asked them why they didnt put a note to say it was a mistake or even remove all the promotional pamphlets as it was misleading. The person who was assisting me was Abongile who then referred me to the Aerial Manager, Maxwell who in turn told me that the promotional manager , Christina will help me. Maxwell eventually called me and promised me Christina will call to sort this issue out but I am still struggling to get any help from Spar.
