Iowa Steak Company Rancid Meat Oklahoma City Oklahoma

A week ago, a guy knocked on my door.  He almost forced his way into my house.  He said he was selling steaks and I said no.  He brought some up and said since the box was open that I had to buy it.   I gave him a check and got the meat just to get rid of him.  The meat is rancid.   I called and the company said that there was a 72 hour window to get cash back and that the information was on the receipt.  The guy did not give me a receipt.  I am on a limited income and am stuck with $150 of meat that I can't eat.
