False Advertising AGAIN!!!!!!!!

I went to purchase Pampers at Clicks Kerk street today, I get to the section and I see that it says pampers premium is on special 1=R189.90 2=179.90 a bag (there is no size showing) I then get to the counter and to my surprise im being charged R299 a bag..i then call the supervisor and he tells me that its not that particular size and that its only where the special offer cards are stuck I mean how stupid is that. Why did they then not put the size on the offer. Its false advertising and I was also humiliated by having to put those nappies back not because I couldn't afford it but because I was not willing to pay for a product that was advertised differently. This is not the first time it has happened at this particular Clicks and I feel I should contact the Consumer Goods and service Ombudsman, the porridge also shows R39.99 but I get to the till and its R50.00 I understand its not a lot to lose but at the end of the day I have the right to pay the amount advertised and also not get attitude from the staff when I question them. I think I should also put this on Facebook and contact the news paper to let them know how that branch is ******** us every time. This is Pathetic really!!!!You may even contact the cashier that helped me because I even shouted at her and it was not even her fault for her Supervisors stupidity her name is Renesca Solomon
