No stock on delivery day - Decofurn Northriding Shoddy

Very bad service. On the day of delivery after the driver calls to ensure someone will be home I get another call an hour later saying they don't have stock! How do you have an entire week from point of sale to deliver date not to know there is no stock? When the sales person called on the dY confirming there is stock. A day before or two days before but not on the day of delivery when all preparations where done in expectation. A zero score rating from me
