zenhotels.com
Got 2 BRG submissions (against zenhotels.com rate) rejected. They claimed bookings on zenhotels.com can't be confirmed immediately thus against T&C. So to prove them wrong, I literally made a booking on zenhotels.com and replied them with screenshot of my zenhotels.com confirmation and charge on my credit card. They still insist on it's against T&C. Ugghhh...
