It could be that you are new & if it is something that someone won your auction the credits will not show up until that person puts on the auction that they received it.
Just as Maryawalker said listia holds credits in pending status like a escrow account until buyer indicate the got the item and then you get the credits. Stay on top of the feedback too both theirs and yours. Keeping a 100% rating helps you win your badges and get your seller wings faster. One you do then you can use other features such as Get it Now which is a instant purchase that ends the auction. I wish you lots of success. Listia is great but like everywhere there are those that try to spoil things. Ignore or block them
