Expired goods

I went to Woolworths in Kenilworth & bought a few things in their food market section one of the items i bought was the pack of Portuguese rolls & when i got home already made use of some of the rolls i saw the best before date was for the 10/02/16 & i made use of it on the 11/02/16, the reason why i didnt check the expiry date is because of the quality if Woolworths products & didnt see that one coming
