Rear retaining wall damage from tree

Our read yard has a lot line retaining wall which has been damaged by our neighbor’s large tree root system. The wall is cement and over the years, the roots have pushed the cement wall into our yard (it’s buckling).

There are a few issues here:

1) the neighbors claim that they have no responsibility for the damage

2) the cement wall is impinging onto our property and will need to be back-filled, the wall removed and re-poured with re-bar

3) they won’t let anyone onto their property to inspect, even though the wall is on our side of the lot line

Who in the city can we turn to get resolution to both the lot line wall and how we can fix the damage without having to sue them.
