Rotten ice cream sold

So at exactly 14:06 today we went to go buy 2caramel cup swirls with my colleague. On our way back to the office she complains about the ice cream being off and I said to her it must be your taste butts. As we arrive in the office I then start eating mine and indeed its off. As now I had to rush to the bathroom vomiting due to expired milk sold to customers. I'm now sick my stomach is uneasy because of this. I want to drive back from Longmeadow to Sunnyrock but my time and wasting of my petrol will be too much for just a 39.80 ice cream. I have the receipt and well unfortunately the ice cream is in my bin. I have pictures aswell
