County fair poor quality standards

I recently purchased a county fair product from my local spar and upon using that product to make my son's lunch discovered that the product had mold on it but it's expiry date was set for December.keep in mind I bought it on Sunday and tried using it on Monday.I was upset at the time and sent a email to the company but since then I haven't received feedback.i am very disappointed in the company and understand it does not value it's customers.I paid it's price for the product and expected quality for the price.I am disappointed in County fair health standards seeing that something like this could leave their company and make its way to my sons lunch.
