Rick Hancock ABIart Consigned my Leroy Neiman artwork to sell for me, then disappeared, no forwarding info, phone disconnected, no contact Torrance, California

I sent my Leroy Neiman art pieces (2) to this company on consignment, with a signed agreement that they would sell them for me.  This took place in January 2010.  They contacted me several months later, asking for me to accept a lower price, which I agreed to do, knowing the depressed market situation.  I tried to call their phone number yesterday - Feb. 8, 2011 to find their phone(s) have been disconnected, no forwarding numbers.  Their website is still up and looks active.
