MEGAKID III, is there any specific content (files, et cetera) on these wikis that you object to? I know that you've been on chat in the past seeking the deletion of some old files you'd uploaded. If this is the case, Staff may be more willing to delete the specific content if you link to it (through Special:Contact/general).

If you insist that the wiki must be deleted, then as said by Trellar, Special:Contact has an option for closure of wikis. Know that Staff have deleted wikis in the past, even ones with a little bit of content, but these are quite large wikis.
