What a t***er. Total bully.
I think you need to take on board all the advice here ggranny. Stand your ground (if you'll pardon the semi pun) and make it clear you're paying for nowt, and you're not happy with the situation, and will be seeking legal advice. Sometimes that's enough to make them realise you're not a pushover. If the worst comes to the worst, you can disguise it, but don't let him browbeat you into paying for his wall.
Of course, some folk just think they can walk over others, and make their lives miserable if they don't get their own way. If he thinks you'r e easily intimidated, he'll just push his luck. If you have any family memebers or friends who can be with you for a bit of moral support, that might help.
I wish you luck, and let us know your progress. We can offer some support, at least, if not actual, practical help.
