Ergeon review: Sucks

I had fence put up 2 months ago. Sitting outside with a friend and breeze came by and one of the 8 ft sections fell down. When we went to pick it up it was held up by 3 rusty nails on each side of the panel. What? I paid for galvanized screws. How is this supposed to make it thru a hurricane? No one is responding to my calls or emails. My fence is under warranty but I wanted to know why there are 3 small nails (rusty) on each side of this heavy 8 ft section?
