As I understand the process, Accor Customer Service receives the BRG requests and if the BRG is valid, it then e-mails the hotel to advise that the hotel should modify the rate. So, I recommend that you call Customer Service to confirm that the BRG was approved and did they send that request to the hotel. If so, I suggest that you then e-mail the hotel's reservations department directly with the information. The hotel will likely respond and if not, you can call the hotel directly to speak with their reservations department. I've done several BRG with Accor and each time I've had to take this approach. The hotels seem to ignore the BRG approvals that come from "Cust Service" and instead the customer needs to follow-up.
