PnP Mthatha Lies & false advertising

Hi, Yesterday I went to PnP Mthatha at BT Ngebs to buy myself and my family a birthday cake for my birthday, I saw the special on the "Black Forest" I repeat "Black Forest", to our disappointment and shock the cake was a "vanilla cake", we were and are still discusted by the false advertising and a waste of my money but most of all my day was ruined by this ****.
