Best Choice Products Shipped a desk chair with no back to the chair included Ontario, CA Internet

Ordered a desk chair from Wal-Mart.com; provided by and shipped by Best Choice Products.  The chair arrived in box without the back of the chair enclosed.  It is unbeleivable that a part so large could be overlooked.  When I called the customer service number the automated system informed me that they don't do phone calls and that I would need to e-mail them.  Haven't heard back from them yet.  I find it unbeleivable that a business could be run so poorly.  What good is a chair with no back to it?  No person-to-person customer service.  This is clearly not a company that anyone should be eager to do business with.  It's like selling a car without wheels.  I hope that they, or Wal-Mart will make this right, however it will most certainly be after the holidays.  - Andy, Vero Beach, FL
