Pampers special

I am really frustrated about the service I got today at pick n pay Mall@Emba. There's a special running for pampers that has started today. Pampers cost R178.99 for S2- 94 as per your adverti*****t in the paper. They scan R300, they told me it's a value pack even though the paper states clear which size and how many. I asked for the value pack they told me it's won't be the price because they are 68/66 inside of which the paper states otherwise. I wake up in the morning for this special only not to get anything and refuses to assist any further. I'm really disappointed and slowly losing me as a loyal customer. I will start to shop where they will appreciate me and give better assistance.
