What Our Customers Say
You guys are the best. Your customer service is top notch. Not only this, but there was another time that I had a question about the Iconic Industries lower and someone called me personally the very next day. But you rock! Thanks again.
I know my order wasn’t very large, but I wanted to take a second and let you all know I appreciate level of service you provide. I had to call your sales team to verify the product prior to order and the gentleman I spoke to was very helpful. This order was filled and shipped very fast. Top notch! I have never used your company before, but you are now on my recommend list!
Thanks for being a super hero to this guy!
I thought since I ordered it at 12 AM EST that there would be a difference when it would be shipped. I would also like to say that your customer service is awesome and I will definitely be shopping with you again and telling my friends of your company.
It’s refreshing to know there are companies out there that with superior products that are on the ball. I’m amazed how fast your product got here (only about 3 & 1/4 days). It speaks highly of your company and employees proficiency. I will be a future customer of yours from here on out. Thank you so much again!
