Appeal wrongly thinks POI is on school property

I had a nomination for some public allotments rejected by the community. So I appealed.
Niantic have just rejected my appeal saying it’s on school property. It isn’t. It is next to a school but the allotments do not belong to the school. I have linked to the local council’s info where it states they are public allotments.
Niantic got it wrong. How can I get this fixed please?
