Data point - I was successful in getting TCB to pay. I originally booked a country inn through TCB, and it tracked. Then submitted a BRG claim, got the lower rate, and it automatically showed up as a separate line item on TCB. The BRG rate just displayed as payable a day or two ago, and the original rate I had booked at showed rejected - which is correct. So YMMV. Lucky me, I guess
