still being sold 7months after \best before"date"""

On Monday morning (18-05-2015) I bought my cat a 500g pack of whiskas cat nuggets from Spar, gateway ,just to discover when I got home that the best before date was October 2014! This is absolutely unacceptable. I was also charged more than the advertised price ( which has happened before) on 3 different items on Monday which was rectified after I noticed the price of the items on the screen however selling pet food that is no longer good is what has pushed me to the limit, my cat is family to me and if anything had to happen to him I would be devastated. I never expected this from Spar. From a very unhappy customer
