I have taken parts back to my local supplier that were of poor quality or needed to be modified to be able to use. What I got was a "deer in headlights" stare or a comment that they had sold many of them and no one else has had a problem. (It must be me). I'm sure they put them back on the shelf with no further action taken. That's about as good as it gets.
