So I was bidding on a 650 cam, as i've been looking for one for some time . And I was high bidder. So my problem is, I just went to check on it, and it's not in my bidding history, it's not won, or lost.... what happened?

did the seller pull it? shouldn't I be notified? Ugh, been looking a 650 cam for my 550 for quite some time now. figured I had it in the bag...
But according to my Myebay I've never even viewed it, it's just gone.
anyone have something like this happen?
