hi guys,
wish I read this thread before finding out myself the BPG is useless. Booked a hotel, found it considerably cheaper on booking.com app, took a screenshot, sent it. Got an answer 24 hours later (should I consider myself lucky?) saying that there is no date on the screenshot saying when it was taken. I'll just cancel the booking, but honestly, this just very efficiently (double) destroyed the trust I had in accor.
