Bargains Appliances Factory - Milnerton Cape Town did not Deliver my Hisense Bar Fridge

Bargains Appliances Factory - Milnerton Cape Town did not Deliver my Hisense Bar Fridge. I saw the advert on Market Place and saw that the bar fridge was R1 000 and I showed the Interest. They provided me with the quote that states R 1 250 and I paid immediately. When its time for Delivery they said I must pay R500 extra as the fridge was on special and the special ended today during the day. I don't have that R500 I just want my money back from those ****mers!
