Our neighbour tree has badly damaged a party wall.I asked her if we could go halv6on replacing it ,we live opposite a primary school,the children have to walk next to it .The response was violet and aggressive.We have paid 2 and a half thousand pounds to repIr the wall thinking that would be the end of it .She is working from home ,telling our builders what to do and secretly filming them .She had my cat in her house for 2 years and has destroyed my plants ,what can I do ?
