Woolworths

I bought some salmon at woolworths cradlstone mall branch. As soon as I got home I put it in my freezer then about a week later when I defrosted it in the fridge the packet was all blown up. When I returned it they said they can't refund as It was past the expiration date and I should not have frozen it. I always buy meat and fish and freeze it. Nowhere on the packet does it say do not freeze. R150 for a piece of fish is not cheap to just throw away. Woolworths your staff at Cradlestone mall are rude and have no customer relations.
