I try to understand what happened:
A guest sent a booking request and also ask for a discount (the guest should have sent an inquiry !)
You did not want to offer a discount and let them know if they want to continue with the booking request.
(Better strategy: ask the guest to withdraw the booking request within 2 hours, otherwise you will accept it).
Now you are wasting a lot of time waiting for this guest to respond (or never respond), keeping the dates blocked.
