If its their fence, its up to them to repair it, not you. I can't see anything attached to the fence, and if it was the plants I think they would have found a way through the gaps, and your plants aren't doing that. Could also be that the posts are now rotten, looking at the colour of the panels.
They're trying to pull a fast one, and if it bothers them so much they know what they should do.
If you wanted to be neighbourly you could offer to pay a third or half, but if they are not being nice about it, don't.
