Clicks Misleading Sale price

I went to Clicks Lenasia Signet, as I passed the electronics aisle there were about 5 double bed electric blankets priced 189 I immediately took 2 of them as the price looked good. As I paid it appeared to be around 600 I refused to pay that price they called the lady Manager who couldn't assist as I reasoned that the price I see is the price I pay she said it might be the customers fault I asked her to check cctv so as to see which customer could that be then I was told they don't have cctv. I asked how does that become my problem then they called an arrogant Store manager by the name of Tumisang who asked me if can't I read the fine lines stating that's a single bed to be true I felt humiliated as I never read any fine lines as what's visible is the sale price. Really if its customer's fault why didn't the manager check his merchandise as I feel is this misleading & store manager should have taken the full responsibility of his *********** staff rather than let me suffer their fault.
