One of my neighbours did what your neighbours did and installed a full patio stone backyard changing the drainage. Neighbour to his left called the town and said it's causing flooding near and into their basement. Town came and ripped it out. He literally came home to weeping tile ripped out laying on his driveway. Now that was 15 years ago. Try calling the town, maybe they send someone over. I can tell you the neighbours have not spoken since.
The Town of Milton is often very helpful with things like this. But, this may not be the case for the OP because it does not sound like the home is effected.
Regardless, good advice, a call to the town can't hurt.
Under normal conditions - it's even better to take some photos and visit town hall.
