Exactly. And the hotel just waives it off.

That's the problem with Accor's Business Model: they rarely own the hotels and just manage them for their respective owner.
The booking center is dispatched to each hotel and is not centrally controlled by Accor, hence no leverage or negotiation power over the hotels.

The only way I managed to get Accor BRG to work as intended was to escalate privately to Accor Management staff, each time.

It's a very broken system and they should either give up or improve it.
