Query: Something went wrong

The previous case of this product that I bought here before was 5-star excellent. The last shipment had nothing in common with the previous. Many of the "crisps" were flat, hard, and crackly, and many had a slight burnt aftertaste. There was much less of a "cheesy" flavor than before. I think manufacturing/QC let them down.
