Misleading information

I am disappointed in the advertising clicks has on their promotion. Today I went and purchased nappies for my 2month old baby upon arrival at the nappy section I saw their sale adverti*****t which stated "2 for R179.99" but when it was time to pay at the till point I wa informed the total is R359.98 which I didn't understand because the signage stated R179. 99 for 2. I could only take one but which I ended up paying 189.99 for which still makes no sense to me. Please clicks @ Clearwater mall stop misleading people with these sales that make no sense I am indeed disappointed
