My Adidas Samba Shoes Order Still Missing After a Month

I placed an order with Adidas on September 28th, and it was supposed to be delivered on September 29th. However, the order hasn't been shipped yet. I waited a really long time for the Samba shoes to be back in stock. Finally, on the morning of September 28th, they had all sizes available, so I went ahead and placed my order. Even though a whole month has gone by, whenever I asked, I always got the same answer - "we're still waiting for more stock." Why would you display a product that you don't actually have in stock? So, if an item is out of stock, how can customers still get it? I don't want my money back. I just want to get the product now. I bought three pairs of Samba shoes - one for my spouse, one for my child, and one for myself. But it's been a whole month and I still haven't received mine.
