Dear Charles, I am aware that from the conversation you had with my colleague that you opened your Carrot Cake after it's best before. With all natural ingredients and packing methods a short shelf life on certain products is to be expected and we list all this information on our product pages as well as on the product itself.
Carrot Cake remains one of our popular products and I hope you feel able to try it again, opening and enjoying it within it's best before. Kindest wishes, Jess
