Samsung DA29-00003G Refrigerator Water Filter, 1-P

This filter no longer fits (as it used to for years) in our 20-yr old Samsung refrigerator... there appears to be a new design change to the fitting (or, a manufacturing defect?). We don't know why Samsung would be unaware of this, and provide no information about this when we call them to let them know about our problem. Additionally, we had set up automatic purchases for this filter (every 6 months). We need to figure out (from Amazon) how to stop any further deliveries of this filter (scheduled to be received IN ADVANCE of the old filter going bad (which puts any we receive beyond a return date, if/when we find these filters no longer fit!). Keep that in mind if you have an older Samsung refrigerator (our old one has been extremely reliable for 20-yrs and still going strong. I suspect new Samsung appliances will NOT be as reliable as our old one). Today, (we all know now) big companies are very much beholden to their stock holders (and not their customers). Unfortunately, the decisions companies are making now-a-days are NO LONGER in the best interests of their customers. It is only 'fortuitous' when Stock holders AND customers benefit each other. Companies must come to understand why their current business models (stock-market driven; AI-driven; subscription-driven; auto-call-center managed; etc) are UNSUSTAINABLE in the long run... doomed to fail. Peoples lives, the greater good (living things), MUST ALWAYS come first. It really is every little thing (combined) we have to deal with (in the real world), isn't it?
