Customer service is horrible.... Horrrrribbbleee!! I request a customer installation of a doggy door into a glass patio sliding door, not the most cheap job. Initially I drove over and spoke to a guy named Chance, he told me what doggy door I needed, I picked it up at Home Depot went back and dropped it off with Apache Glass. I took time out of my day to scheduled and have Mike come over to measure the door. 2 weeks go by and no follow up call or anything. I call and talk to Matt, Matt says he'll see what's going on and get back to me. 1 week goes by so My wife calls and talks to Matt he tells her the same thing. So I call back after another week and talk to Matt he says Mike says the door or job won't work because our patio glass was too thick. So I drive over there and pick up the doggy door I purchased, while there Matt is telling me that he was waiting on Mike to get back to him and apparently Mike knew this job was a no go after he got back to their shop and that was about 3 weeks ago.. The bafoons are freaking thick in the head.... I would suggest you look somewhere else for business... seriously. It's a circus here... chime in the circus music in the background.
