Walmart worst customer service Internet

Ordered 3 tv's from walmart.com.  I chose and paid for recorded delivery since I needed the tv's by certain date.  Got an email confirming the items we shipped and would arrive by January 11, 2014.  They didn't.  On Monday, January 13th, I emailed walmart to let them know the items that were supposed to be delivered on January 11th were not delivered.  All I got back from them is an email about their 1 hour in store pick up guarantee.  I received one of the items yesterday, 3 days after it was supposed to be delivered.  The other 2 are still in transit and have no estimated delivery date and no explanation from walmart.
