So basically my mother has been living in the same house for 23 years with no troubles with any of her neighbours prior. About 6 months ago a South African couple moved in next door and proceeded to do extensive renovations (most without our or council approval). Some of the renovations include knocking out the walls on his side of the house (its a semi), putting over a metre of soil in his backyard so he can now look into our backyard and kitchen, installing a airconditioner right next to our window and finally today he cut down a tree on our property that has was planted when my grandfather died 4 years ago. We have spoken to the council and they sent out letters to us and other neighbours, however the neighbour went out and sorted through our mail and removed them from the mailboxes.
