It does not seem likely that he booked it under the Flock room block. The text of the screenshotted email: "called on my behalf and canceled my hotel reservation that I personally made on Hilton's website. They also have not refunded the reservation, as it is now associated with Flock in the system." It doesn't clearly state that it was part of the room block at Benn's initial booking, and it implies that the booking was not associated with Flock when the initial booking was made.
