thanks for posting. the best way to establish what happened is to reach out to the boost customer care team to see whether you were accepted last year on the scheme or not.
boost haven't opened their application for the WHD this winter so keep an eye out for it. if you search WHD in the search bar at the top of this page, one of the other posts contain the link to preregister your interest in the WHD scheme when it opens later this year.
