If you sent a request but changed your mind or booked someone else, you should cancel the request to free up the DJ's calendar.
Before a proposal is accepted, you can cancel the request at any time without penalty. Go to your Bookings tab, select the Pending or Proposed event, and click Withdraw Request. The DJ will be notified that you are no longer interested.
(For information on canceling an already Confirmed gig, see the Payments & Refunds section).
