They have my return flight from the wrong airport over 1000 miles away

I booked a flight from DFW to Fayetteville.  Then another from Fayetteville to Norfolk, and lastly another flight from Norfolk back to DFW.  All in the same week of travel and at the same time with Expedia.  Expedia got me to Fayetteville AR correctly but my second flight was leaving from Fayetteville NC over 1000 miles away instead of the one in AR.  My iteniary says Fayetteville.  It not does show the state.   How was I supposed to know?  More importantly I called Expedia several times.  One call I was on hold over an hour and then disconnected.   I am currently on hold with a supervisor.  This call so far is 42 minutes.  I will never use them again.  I take some responsibility for not noticing the airport code had changed but why would their site default to a different city and why is their customer service so bad???
