Premiere Props Dan Levin and Dawn Rapp they auction off my dead husband's movie props collection El Segundo California

My husband passed away august 28,2014, my husband was a collector of movie props and costumes, a few months after he died I was in contact with Premiere Props to auction my husband's items, auction was held on december 6,2014 and I made $31,755.00 then another auction was held on march 28,2015 and I made $3,000.00, I haven't received money from Premiere Props from neither of these auctions. the contract says 90 days well its been way over 90 days, the persons in-charge and head of Premiere Props is dan levin,  and the other person is Dawn Rapp. they will not return calls or emails, if you do a google search on them you will see MANY complaints from MANY websites, This company is owned by dan levin and he is one of the biggest con guys there are,  as I said just do a google search on dan levin & premiere props and see all the complaints from people that he has cheated, They sold my husband's original Forbidden Planet costume and many other items and has not paid us a penny,
