Blinds To Go

See the installation issues in the photos ,they damaged my walls and they arent capable of taking correct measurements
quick summary of my issues are as follows and photos will elaborate more
My wall was dented and scratched from the installation
The valences were scratched from the installation
Improper valences installation . where there gaps in the conjunctions
incorrect measurements were taken so he insisted on banging to make it fit .. result are dents , scratches and that the blind doesn't even reach the metal frame . one blind came 57 inches wide instead of 58 5/8..so he had to suspend it more so that the role can take the required distance
incorrect measurements were taken this resulted in a more light gap that what was expected and no symmetry even on each side of the metal frame . One side even doesn't reach the metal frame . In other words both sides are centralized and light gap is way to big than what was communicated
He doesn't have proper tools for installation such as the water leveling ruler .. I asked for it when he said that ceiling wasn't the one proper ... ie meaning the ceiling was tilted but we couldn't check as he didn't have the proper tools .. Why is he coming not properly equipped ?
Not cleaning up after his work and leaving the place a mess
