Sell products that are out of stock - still have guts to deliver short order without notifying customer

You delivered my order short of 1 item on the order i placed. I refused to sign for the order and requested driver to take it back, until someone in your company decides to call me and inform me that my order will be delivered short with 1 item and assures me that the missing item is not part of my invoice, then will i accept that order from your warehouse. I wont accept responsibility if anything should happen to the returned order, because your company doesn't have the customer service to call me and inform me of changes to my order due to your LIES - you sell things that you don't have. You put the invoice inside a closed box, how do i even know you have not include the missing item on the invoice. Why are you still selling OUT OF STOCK items on your online shop......
