now having going through my account, no matter how see it I should retain my platinum status,
base on old system: achieve July 2016 + 365 days = platinum renew at July 2017 (however we are migrating to new system). which still Platinum status

base on calendar year: 1/1/2016 - 31/12/2016 (365 days) I earn 25900 points hence platinum status

base on accor plus calendar year which is january,and it not even end yet (my member end 31st January) so 1 year would be: 1/2/2016-31/1/2017 (365 days): which Jan 2017 not even end yet and including this stay (9th-11th Jan) i already have 65 nights, and probably will be over 70th night if this case does not happen. hence still platinum status.

base on the new system, all status upgrade on the previous year will be carried to the following year, status achieve July 2016, carry on until Jan 2018. hence: still platinum status

so until this moment, I only enjoy my platinum status for roughly 6 months. and now I become gold?

unbelievable.

I have given all this fact to accor concierge and the accor plus representative that replied my email. I believe they can confirm all my claims and hope that they can rectify the problem soon. will update again when they replied my email.
