Kmart.com Kmart lost my order, could not investigate or report back to me or issue a refund Internet

 I made a purchase using Kmart.com layaway in August 2013, final payment made October 2013. Shortly after the final payment was made, the status changed to "Shipped" with no tracking. So I contacted customer service using their Chat service and was told they would investigate and get back to me in 5-7 business days.

A few days later, the status changed to "Delivered", still without a tracking number. This time I called and was told they are still investigating and to wait a few more days and someone will contact me.  After waiting again, I called back and was told the same thing.

I emailed customer service at this point and was told to wait until the 14th and they would contact me. Still no response and I have not been refunded. Instead I get apologies that mean nothing. I requested a refund and no longer wish to conduct business with Kmart at this point. I feel like I gave them $92 of my hard earned money to just be thrown away. I'd like my money back ASAP and I'd like someone to actually provide adequate customer service and give me my money back for a purchase they lost and improperly handled.

Kmart customer service does NOT work. I am NOT happy. I will sue for the fact that I now I have to find another way to get my children's school uniforms since I'm at a loss.
