We have ordered hundreds of these panels over the years for various installs and for personal use. Recently we ordered a couple dozen panels and were short some mounting hardware. I called a couple times and talked to a very rude rep, who at one time sounded as though he was going to charge me for the hardware that was missing. Reluctantly he said "Ya, I will get them out to you.". Weeks later, nothing. I was very disappointed, especially with as many panels as we just purchased. Today, I called again as the panels were still sitting on the floor. I talked with Darius Smith, who was apologetic for the previous rude customer service person, and within minutes had a tracking number with the missing hardware on the way. Owning a small business myself, I know mistakes happen all the time. That is fine. What is not excusable is rude customer service. Darius was fantastic and he literally just saved Acoustimac from being crossed off our vendor list. Thank you Darius! You are a credit to your team.
