False advertising of typek 5*500 box

Cambridge advertised typek box 5*500 80g box for R54, 99 during 25/4/19 and 7/5/19. To my disbelief at the store we are told they are out of stock yet the special starts today and that they only have the 500 pages rim for that price and don't have the box forever. The manager Mr Peter Mashino at the Newgate Junction Jhb store with a rude tone said its only the rim not box yet its advertised and said he knows but can only sell the rim not the box as advertised. Well aware of the pamphlet add.
