H Aetolia. 

You could consider contacting the Data Working Group of the OpenStreetMap Foundation (if you haven't already done so), clearly describing the problem and linking to the related changesets. Before doing so, please read the page https://osmfoundation.org/wiki/Data_Working_Group, especially the section "I've seen a problem; what should I do?". 

Kindly note that all Working Groups are composed of volunteers, who dedicate their limited personal time to trying to help with mapping disputes.
