So I didn't realise that existing unused Accor Stay Plus benefits were going to suddenly disappear on 1 Oct. I still hadn't used mine for this membership year, and I had it still showing in my account with an expiry of Dec 2025 at the start of last week. I logged in to try to use it at the weekend and found it's gone. I contacted Amex and they first claimed that it definitely wasn't gone and the changes wouldn't take effect until December - which turned out to be complete nonsense. They have now confirmed it's gone and said there is nothing they can do. After I complained, they then offered me 280k points as compensation - but not until January (coincidentally after my next annual fee is due). I think this is basically the final straw for me.
