TARGET Target Sucks. They ripped me off. Eureka, California

I purchased a shop vac at target.  When I opened it I became aware it was not new.  It was dirty and parts were missing from the box.  I took it back to the store, along with my receipt, and was incredulous at their response.  They refused to give me a refund.  They were extremely rude to me and treated me like a criminal.  As far as I'm concerned they're the criminals.  You don't sell a used item as new.  And you don't disregard your own return policy. They offered store credit but I had no need for anything there so refused.  I was in full compliance of the posted return policy.   I asked to speak with the corporate office and was put on hold for 20 minutes and then told they would not refund my money.  They stole my money.  I have been ripped off.
