Custom Vinyl Lettering Review #20841: the front door of my business

I ordered lettering in black vinly and although it was easy to install the lettering did not show up on a glass door . I filled out a survey on the excellent service and mentioned this (as to help someone else not make the same mistake) and a representative responded that they would replace it with white lettering free of charge. I was not expecting that, i only wanted to let someone know so they would not have the same issue i had. Greatly appreciated. great customer service and business!
