Change of Booking - Fewer Rooms.

Our Guest has changed the number of people staying from 7 to 5 people. 

This means, we have now accommodated them in 3 rooms, rather than 4. 

We have changed the booking on our side, but on Pulse, it still shows the original 4 rooms. We obviously don't want to pay commision on rooms that are not booked or occupied!


Please advise, urgently.
