H & M Fences LLC review: Improper installation of fences

Hector Mangual from H & M fences had install my fence at 121 SW Euler in Porth St. Lucie and it crocked and fell down and the gate fell off , I call him numerous time to correct the problem but he always has an excuse why he could not come . the whole back fence is falling down.

I check and he did not put anything to hold the post in the ground and all the panel is uneven,
