I have had the same experience - they never call back. And same deal, I sold the bag directly within a day of just letting my local friends know it was available.
In all honesty, I haven't had much luck with the big resellers. Ann's was a bad experience (similar to others);
Fashionphile has only sent me hilarious lowball quotes; Jemznjewels I unfortunately did not find to be that nice of a person (sorry
@Notorious Pink ); L'Ecrin not even worth discussing. TRR I would not consign to knowing what they are like to buy from and how they misrepresent items. I have had much more luck selling my bags directly or even on eBay.
