Misleading billing

I bought a pair of wireless skull candy headphones for my husbands birthday today 27/11/2017 and have been completely mislead by the advertised price and what I was charged. The price advertised online was R599 including delivery and I have been charged R750. I have taken a screenshot of the advertised price and the same product being charged at 2 completely different prices. A couple of hundred Rand may not be a lot of money, however it is the principle of it, it feels like my money has been ******. I am not sure if perhaps there is some sneaky fine print that I missed or something, but it is very misleading and I am sure I am not the only customer that has had this happen to them. I will not be recommending their website to anyone.
