If the "relocation team" prove to be useless, which lets face it, won't be a shock. I would contact the other Curio and the Hilton Paris Opera and explain the situation. Call in and ask to speak to the Revenue Manager. Offer to send the emails you've received. It's within their power to open up a standard redemption for you. I presume that won't be anymore expensive in points than you originally paid.

This could be an easier way to resolve this. You could also ask this "team" to do the same thing but I would be keen to resolve it myself.
