Expired products cut up and sold

On Saturday 17th August 2019, I purchased sliced smoked chicken from the deli as pnp promenade in Mitchell's plain. It was put into pur freezer on the day of purchase.. when used on Monday 19th of August you could taste that this was off.. I'm guessing that the reason it was cut up in little plastic containers was due to the fact that it was close to expiry date. Problem is though there was mo sell by or expiry date on the pricing label on the container
