Non delivery of bulk order!

I have ordered fridges from them. I have paid in full because they confirmed that they have stock and deliver quickly. I waited until the Tuesday and they did not deliver. After I have to contact them they promised the stock is on the way from 'Cape Town' and will be delivered the next Monday! Yesterday was Monday and nothing!!!! It is end of business day today Tuesday and still no answer. The don't reply on email, not do they answer the phone! Please assist!
