Accor has a partnership with Europcar. This is the dedicated landing page: https://partner.europcar.com/accor/en
You may get a discount on your rental and you should earn accor points based on how much you spend with Europcar.
I've done multiple rentals now as there is an Europcar location close to where I live, sometimes I get a discount but not always, but I've never received accor points.
So far I've kept using Europcar because it's convenient but now their canned replies start working on my nerves. "your rental agreement XXXXXXXXX is not eligible as you benefited from a type of contract which is excluded to earn miles as specified on the rules between Accor and Europcar." And that is all they say each and every time. If you push for more info they point to the T&C on the page above which doesn't make you any smarter.

I wonder if anybody has ever received accor points from Europcar and how they did that?
