False advertising

I ordered a watch and my order for canceled after everything was confirmed,I sent an email and never received a reply ,when I called I am told reason is it is low in stock and yet being advertised and I only received the response to my e mail while on the phone with a lady that sounded like she's sleeping. I was further told there nothing that can be done. Makes no sense as I still want to purchase the item that is showing for sale on their website but getting no help . This is misrepresentation of a sale .
