I take it you did a print screen or otherwise got a hard copy of everything about the ressie so far. I take it you already have a confirming email showing the flight dates and times, flight numbers, fare, names of persons traveling, and so on.
FIrst thing to do now is go back into Travelocity and see what the ressie looks like as seen on their website. The ressie either still exists or does not exist. Print out everything again as it stands now and write the current time and date on these papers with your own handwriting.
You could see one of three things:
1. The ressie is still intact at the fare you expected.
2. The ressie is gone.
3. The ressie is still there but showing a higher price.
If the ressie is still there at the original fare I would sit tight for a few days but check it again and print it and manually date it again every day. Press the refresh button every now and then just to be sure you are getting the latest information from Travelocity as opposed to displaying an old saved (cached) image from your computer hard drive. After a few days try to change seat assignments just to stimulate their system into doing something. Call the airline itself asking for a written confirmation which they generally send even for electronic tickets.
If the ressie was cancelled do a print screen also. You should have no problem getting a full refund. Work along the assumption that they cancelled it and not you.
If the ressie is there but showing a higher fare, immediately call them and tell them to either put back the fare showing on your yesterday's printout, or cancel it. Keep calling until you can see the results and print them on your computer.
Do not book new flights until you have written evidence (such as a print screen) of the old flights' being cancelled by them, not you.
Save all of the paperwork

Occasionally when you book a flight, whether through a local
travel agent, an on line agent such as Travelocity, or directly with the airline, the written confirmation does not show that the flights are really confirmed. There should be the actual word "confirmed" or the word "OK" next to each flight segment to indicate that it is indeed confrimed.
"Print Screen" is just one of several methods of getting a paper copy of something you see on line. On most systems, pressing the "print screen" button is just one of several steps needed before the paper comes out of your printer, you may find alternate methods easier.
