Phoenix
I came in for a somewhat minor issue at the 67th ave and Happy Valley location. I'm not from that area. It was near closing time. They helped me , and provided a warranty on what needed to be fixed(most places don't -from my experience) I was surprised not only at the warranty but at the outstanding customer service. While waiting for the fix I overheard techs talking to other customers. Everybody was honest. They earned my business. I came back the next morning for clarification on something and the service was still great. It wasn't something "Oh great there they are again" amazing!
