yahoo travel service

I was looking for a flight from El Paso,Tx, to Phil,Pa. Yahoo travel had a

very good deal. I filled out all info, including credit card and submitted

it. After several min. a screen came up that info didn't go through. I

restarted the process and found the fare was no longer there. I then chose

different dates that had the same discount. Again I went through the whole

process and again was blanked out. I cannot find anywhere on Yahoo to

complain. I lost out on a great fare because of their poor site.
