Spoilt polony

Purchased polony from pnp Phoenix, but when I got home the polony was spoilt, polony had an expiry of February next year but was already spoilt. On the till slip it says ostrich mince. Very disappointing for a store like that to falsely advertise the label. I'm vefy disgusted with the poor service. Contacted pnp head and store got ref no but nobody got back to me. It is very disappointing for pnp to stock rotten things epically after the outbreak of listerious. The management is also usuless when it comes to customer complaints. I am going to publish the photos in the local news papers as well. Very disappointed customer.
