Discovered - currently not indexed

According to Google search console three of my pages have been "Discovered - currently not indexed" for two or three months. They say I just have to wait and it will be fixed. Well I think I have waited quite long enough, how can I get this fixed? My eight other pages are fine, what is wrong with these three? Can and will Homestead help in some way? Is there anything I can do to get this fixed? I am losing business over this. As far as I know I have done exactly the same thing with these three pages as my other eight pages which DO show up in Google searches.
