False advertising

I was at Elite Food Town in Gatesville Athlone to buy nappies for my son I went there thinking I would pay the price I saw on the catalogue posted on there website which was R119 for 50 huggies size 4 but when I got there the ticket said R119 for 36 Huggies spoke to the manager but he was no help I told him this was false advertising on there behalf but all he said was they don't have stock I ask why the the ticket shows 36 and ad said 50s I was told right price wrong picture Manager name is riyaad I feel this is unfair and would like this to be sorted out I work for Woolworths and this would have been sorted out in the customers favor.
