Cell C it on the brochure doesn't mean you get it

It seems what Cell C advertises and what they do are clearly different. Firstly the phone I wanted on contract wasn't available and out of stock and I wasn't kept up to date so I eventually chose another contract on Monday 13 July with another phone and on the brochure it clearly indicates that a free cover and screen guard is included. I was then informed by Angelo that it is a printing error. When I asked him if it is false advertising he said basically yes. I was informed by him that it was a mistake from Samsung and their manager informed them it was a printing error. However on Wednesday I contacted 2 other Cell C stores and asked if they included the cover and screen guard and their reply was yes. I was even informed that the message was given to all branches. When I asked if the message would have been available to the branches by the 13th of July I was informed that that would have been the case. Thus false advertising seems to be a part of Cell C service at Kolonnade Mall. I would like to receive my cover and screen guard as was advertised.
