Rotting bread before expiry dates

I bought two loaves Albany bakeries bread from checkers hartswater. And before the expiry date, both loaves smells rotten, with strong fermentation smell. For which the bread was stored in a cool, dry and dark cupboard, but still rotted. My assumptions is that their expiry dates are over reaching or over extended pass the actual shelf life of the bread. And it has happened like this several times. Which makes me question their integrity. They have a superior taste and quality but I just have to move from their ************* practices, if that is the case. Because I had to throw away that bread, which I bought with money several times.
