No stock and delayed delivery

I ordered a dining room table online on the 29th July. About a day or two after ordering it, I received a call from Coricraft to let me know that they had no stock and that the shipment would be coming at the end of August. I called the first week of September to find out when I can expect the item and they said the shipment was arriving the 16th September. I then called again (18th September) to be told that shipment is only arriving on the 26th September! I have been in my new home for over a month and half with no dining room! This is absolutely appalling and a disgrace.
