Cuisinart, Inc. Cuisinart Food Processors Cuisinart Won't Admit Design Flaw East Windsor, New Jersey

I have a 16 cup Cuisinart FP from Williams-Sonoma. There is an inherent design flaw in both the work bowl and lid of this unit.  Food gets stuck in the handle of the work bowl and the locking mechanism of the lid.  Nothing fits into the handle or lid short of dismantling both pieces I cannot reach the food residue.  Cuisinart will not stand behind their product if it is out of warranty even though this has nothing to do with breakage or damage.  I spent 15 minutes on the phone with 3 different customer service representatives to be told I would not be receiving a replacement work bowl and lid without charge.  The first agent told me to soak the bowl and lid in very hot soapy water which I did for four hours.   The food residue is still trapped.   Agent #1 also said they would send me a new work bowl and lid if the soaking did not work.  When I called back to report the failure, I was told I would not be receiving a new work bowl and lid although these were promised by the first customer service representative.  Cuisinart will not acknowledge/admit this is a design flaw.  I have photos of this problem if needed.
