I know the feeling, had the same happen with another person's zone myself when I was planning to build a network of sky-bridges...
Just have to bear with it though unless you can sort something out with the zone owner, chances are coleg has plans for building in it, even if it is a big zone, so it wouldn't be fair to go and remove, or resize someone's zones without them knowing.
