A family member who also owns some Accor shares but wasn't previously an A|Club member signed up earlier this month. Her new Platinum card has now arrived and differs from my card in a couple of details. A small text box containing the words "Club des Actionnaires Accor" is located on the back next to the customer service numbers (which were also missing from the reverse of my card).
Bought some 51 Accor Shares today and filled out the online application form in French for the Accor Shareholder club and submitted it online.
Now I will just wait for their e-mail and submitting the proof of 50 shares .
Hoping I will get Platinum status .
Let you know if its working.
