Seal broken and older product — why can’t I return it?

I purchased other types of mushroom capsules such as Chaga and Cordyceps which had their seals on and had later expiration dates. This particular one had the seal broken and the expiration date was far earlier (a year +) compared to the other two. Also, the box was worn out and I could clearly tell the item had been returned and sat on the shelf for a while or handled a lot. It says I can’t return it, so I’ll be contacting Amazon to somehow resolve this considering the cost and the item’s condition.
