Advertising errors on Crazy Plastics part.

I went online as I was searching for plastic storage containers. I found a special and was eager to place an order. It told me to go to there online portal. But as always when I see a price and it seems to be too good I would phone to check with the store. I got hold of a gentleman by the name of Gregory and WhatsApp 'd him the picture on the website. On the messages you can see that I asked him about price three times which he avoided to answer. On and off we were chatting and he asked me to refresh my computer which I did. I then went online again and searched the product and it still showed the special. As it was 17h00 I decided not to chat further. Friday morning I called the Head Office in Benoni and spoke to a gentleman by the name of a Matthew and he said he would get Laura the Marketing Mngr to call me, needless to say I am still waiting. And guess what the next day the website was updated. My question is should Crazy Plastics not honour the item that I sent? Afternoon all it is them to blame for not updating there website.
