Thanks All. I took a look and I guess they have me by me balls on this one. I closed the auction and asked that they not do anything to me FF account as I clearly had no idea this was wrong. There are vouchers, etc being hawked on ebay everyhwhere!
I was planning on tranferring the miles to an account which the airline promotes on their own web site. Seems like a crock that an airline can bait me into buying all kinds of junk to accrue miles but when I want to sell them, i can get busted. Oh well.
Hopefully the airline forgives me for a rookie mistake. I really dont want to be docked miles, etc.
