Direct Solar Supply Solarack USA Inc Did not ship. Refused to talk to me. North Hollywood California

I ordered racking for solar panels from their website. The shipment was short 62 pieces with two more items arriving damaged. I called them and was told that the person who handles these matters was not in but she would return my call. After four hours I called again. I was given the same response. I asked if my call would be returned this very day and was told it would be. They asked me to e-mail photos of the damaged items, which I did immediately. At 5pm I called them a third time, as it had now been another 3 hours since my last call. I received an automated answer stating they were now closed. I then sent them a second e-mail requesting to be contacted in order to resolve the shortage. This happened in August. 2017. As of December 2017 I have heard nothing from them. This had been my third purchase from Direct Solar Supply. The previous times had both been short, but upon contacting them, they always shipped the missing items. For that reason, and because they had quality racking at a good price, I kept buying from them. No more. I do not know why they are unable to count correctly or why they refuse to communicate with me. Common Core perhaps?
