Bed bought online a week later still no delivery and empty promises

On black friday bought a bed online it clearly stated 3 days delivery. Sunday received a call stating they didn't have the bed in stock which I didn't understand because it was available when order was placed.They told me maybe they'll have it on Thursday. Today its Saturday I have not received any correspondence from them I left my details on their Facebook profile they promised to call but nothing! I have had to call the call centre and they promise to check with warehouse in Pinetown bt I have not received a clear answer. If I knew I would have placed my order with another company that knows how to treat its customers.
