false advertising on S26 Alula gold post discharge 900g

Today around 1pm at Dis-Chem baby city Trade Route Mall, I wanted to buy baby formula S26 PDF Alula gold(post discharge) which I saw on baby city website for R244 normal price but when I get in the shop it's R270 then I tell the lady and even show the lady that works at baby city. She then said she will confirm with the head office as it's scanning R270 on her side and the head office said it should be R270 just as shown at Dis-Chem and not what Dis-Chem baby city has but they are aware of the issue on the website.so the lady said unfortunately she can't give me with the price they showed on the website which was confirmed by the lady's(works) in store & online team at baby city that it was a baby city page not a **** website. So in conclusion the lady said it's not the error at the shop but the people from website/online. What I didn't like is that they didn't apologize for the error on the website for the in store purchase but said it's not there problem. And now in the evening when I check it again, it's now changed to R270 on the same website page. I am very disappointed with them.
