Calling Customers "ridiculous" for ordering something at the wrong price on their website

They posted a Western Digital 3Tb hard drive on their website for R29.00 and i placed a order for one after a email sent to me saying they will check if the supplier have stock and let me know 3-4 days passed and i didn't hear anything from them i decided to call and find out what happened an argument started where i was told i don't have a foot to stand on and that i am "ridiculous" to think i can order the hard drive for that price. like i advertised the product for R29-00 so i would not recommend. and Would Recommend they Read their Consumer Act
