I did a bit more research. Went to United's website.

So it was a US Airways operated flight which carried a United flight number. This is a very common thing known as a codeshare. You simply read the itinerary wrong. As for the part about the ticket not being issued, if Sam's club was able to provide you with a ticket number any airline should have been able to find that ticket in their system. I mis-connected in San Diego once and even though my ticket was issued on Continental a US Airways agent was able to pull it up and re-route me through Charlotte.
What was the ticket number Sam's club gave you? If you post it here we'll be able to tell which airline actually issued the ticket. The first three digits identify the carrier.
