Really hope that I’m not pulling this story out of storage but I really hope that you managed to get this guy back for doing that to your tree. It seems like extremely reckless and inconsiderate behaviour to say the least about what he did! What if the tree had sentimental value or otherwise?! And it’s worse that nobody else managed to give you a go-ahead to stick it to him and get some form of redress for his actions! Hope to hear some good news about this.
