Snack platter with mould!!

Today I bought a snack platter, and after eating one of the sausages noticed it tasted horrible. When I inspected it I noticed that most of the food are covered by blue mould!! Mind you, the sell by date are only tomorrow!! I immediately took it back, and only received the money back for what I paid for it. No refund as Spar promises on TV as \double\" the guarantee for freshness?? Driving back to the store, ended up costing me time and petrol!! Do I need to place the pictures taken, on Facebook and Twitter?? The store manager Johan didn't care. What if I fall ill?? Do Spar really care about freshness??"
