Well they clearly have done nothing to correct whatever is going wrong between AccorPlus and Le Club Accor.
I was Platinum last year on points. I requalified for Platinum for this year on points
I joined AccorPlus in Aug 2016 and had a Platinum Card with expiry 8/2017.
Sept 1st 2016 - Dec 31st 2016 I had 42 nights. Jan 1st 2017 till today I have had 48 nights - so 90 nights in the 12 months since joining AccorPlus
I renewed my AccorPlus membership this week and my status dropped from Platinum to Gold.
It seems they resolve individual problems but do nothing to fix the systemic error.
