Old sausage

Hi. I would like to complain about pork sausage that I bought today which was old and smelling. I did not notice that the sausage was packed on 2019-09-10 in which I bought it on 2019-09-16. I don't know why you sell such old stuff, meaning the sausage was in your fridges for 6 days. I would like to receive my money back as I had to give it to dogs. Please see pictures.
