Warlock Succubus Quest Bug

Hello! I've been trying to get my succubus and I have abandoned the quest accidentally and deleted the needed quest item. I cannot get the quest back from the quest giver as he doesnt have the quest anymore. I tried checking the earlier steps of the quest and they do not give the quest too.

This is the starting quest

This was the quest I have abadoned, along with destroying the quest item:
