I went, they talk to me but nothing with interaction. The last thing he told me asa I’m ready I meet them at te Harborage. By that time a delete it by mistake and when I came back non of them has something to tell me.

First, usually most of the Main Quests start when you go to a major city, and the prophet talks to you. If they don't have anything to say, like they are stuck at the end of the last quest, try going back to a city to see if the prophet shows up to yell at you that he needs you back at the harborage.

Since you are near the end of the Main Quest, have you completed all the Coldharbor quests? Before you have the final battle, you need to have completed the Coldharbor questline, as described in this thread, where someone couldn't pick up the final Main Questline until they did. https://forums.elderscrollsonline.com/en/discussion/102160/stuck-cant-receive-the-god-of-schemes-main-quest
