My neighbour add his wall at the last moment. My contractor have to add the wall to the edge of the roof's slab.
When I asked for 3rd party opinion, most of them estimate, only 70% of the works were done. This means I was cheated 25% of the contract value.
If you are in my situation, what will you do?
