just park the van outside his house every day Lol.

Set up a some sort of camera and get the evidence.

Show him it dont bother you maybe he will get bored and give up.

Could go the other way of course...

Or go over there calmly knock on his dorr and ask for a word, Then tell him if he wants to carry on like a C**t then you want to apolagise now for youre future actions.

And walk off.

Lol You being calm Would get to him a lot more than kicking off.
