You're not the only one!
I've been Rouge for several years too and I found that I am Platinum under FB. I still haven't got the FB card or kit. Or even a letter. Nothing.
Not to worry though. On my DL flights yesterday and today, the boarding pass said Skyteam Elite Plus under the FB number.
And don't even get me started with the FB service desk up in Canada! I was put on hold when I called. I was busy at work, so I put it on speakerphone and turned the volume down. I finally hung up after 3 hours of being on hold!
Luckily it's a free number here.
