FOOT LOCKER.COM will not refund money or replace item that was NOT sent to me.

On August 16th, I ordered 2 pair of shoes.  On the 24th, I received one box, with ONE pair of shoes inside.  The package was delivered via FED X and a photo was taken at my door.  After contacting company they stated an ivestigation had to be conducted.  A week later, I was notified by email stating that upon their investigation, they determined 2 pair of shoes had shipped from the store and my case has been denied AND dismissed with no replacement or refund.  After speaking two several supervisors, the matter has not been resolved and I am still without the shoes or money.
