Yes, it would help to raise it directly with Bonvoy customer service by email with your folios as attachments. I was told by a Le Meridien hotel that when a stay fails to post, or post correctly, they can only raise it with Bonvoy customer service just like a guest would rather than have access to a system that enables them to correct it themselves. On the rare occasion that my stays have failed to post correctly, I have raised it once with the hotel directly and then follow up with Bonvoy customer service if it's still incorrect and it's always been fixed.
