False Advertising

Why advertise something if you do not have stock or are unable to get the stock. I ordered 2 x Decor Depot 22-25 mm Expanding Curtain Rod Double Ball Endcap Black 1.5-3m and only 1 was delivered I need this for the same room I cant have 2 different rods. What is more infuriating is that it is still been advertised on their website, and there is no-one to call so you have to send an email and hope some-one will get back to you.
