Rotten products

On Sunday 30/08/2015 we went to the brach to buy our monthly fruit and veg, they all seemed fine, get to the till and the cashier keeps on asking us what everything costs and says she doesn't know the prices, today 2 days later we needed to dispose of half of what we bought because it was rotten, I have taken pictures and there was so much \mif"on the fruit that I could probably make antibiotics out of it. How is it healthy to sell these rotten products? They looked okay when we took it but the strawberries tasted funny and all the fruit went from looking fine to completely mif in 2 days so obviously weren't fresh at all!"""
