Ladies, I need some help with a bag I purchased on Ebay. Two weeks ago I ordered a black Marc Jacobs Dr. Q Hillier--I paid a total premium since the bag is IMPOSSIBLE to find anymore (Link to the auction: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330397980091&ssPageName=STRK:MEWNX:IT) What I received was a Marc Jacobs Classic Q Hillier, which, although similar is a different bag (different hardware, leather quality, etc.). The Classic Q Hillier is still available from most stores online; in fact, I had purchased one from Bloomies that I returned because I decided the quality of the original Dr. Q was worth the premium. The listing called the bag a Dr. Q, and the pictures in the listing are of a Dr. Q. Of course I'm going to attempt to handle this amicably with the seller but if they aren't willing to cooperate, how should I proceed?
