There is a new park, Ran Rancho, which does not appear yet in the Pokemon Go game screen. A new pokestop was placed far from where it should be. How do I get support to correct it’s location ? The new pokestop can not be reached, so it’s not possible to correct it in the game. I do have the GPS coordinates from Google Maps of where it should be.
Update, another misplaced pokestop has joined the first out in the field… 
Welcome to the forum.
You can use help chat to request this move from the Wayfarer site.
This is a great guide:
It doesn’t actually have to be an edit that is >10m, but it must actually be to correct the real world location of the point of interest, not for game manipulation.
