Supply chain and quality assurance concerns are usually handled by the manufacturer and distributor, not the end point grocery stores, though. Anything you return to the grocery store is likely simply thrown out and marked as shrink (operating cost of loss), and never reported to the manufacturer or sent back.
If your goal is to let the manufacturer know about quality issues, you need to do that directly. Not through the end point grocery store. They are likely separate corporate entities under the same parent company, in any case, and have little to no communication between each other. The grocery store would be where you could get a refund or exchange, but that would never reach back to the manufacturer.
How it -should- be and what actually happens when you return don’t always match up, sadly. Just giving insight into the reality of how it works from experience working in grocery retail.
