Southwest reward problem

[goofy370]

Hi, I hope someone can help me with this. I have travel funds that expire on 6/24/11. I called to see about having them extended as our next trip isnt until September. I was told that since my travel funds were in one confirmation but 8 different tickets(price changed 4 times) that they are less than 50 dollars each. I was told to make a ghost reservation for around 138.00 (my total travel fund) and then cancel it the next day. Then on 6/25/11 call back southwest and extend it for the 50.00 fee leaving me 88.00 for a future flight. Does this make sense? Can I really do this? I know that Southwest told me to, but I just want to make sure that this would really work out, and if you have done this before

Thanks
