I could not be more impressed with the above-and-beyond customer service we received after a mix-up with our original order. Your associate not only acknowledged the mistake but went out of their way to make it right. I will be recommending your business far and wide and look forward to continuing to do business with you. Thank you so much Megan Dascher Watkins Empire Lighting Inc
