Jacob and Val really took care of me. I needed to exchange an android phone and wanted to get into the new iPhone. They didn’t have the color I wanted and I also had a deadline to get my other phone turned back in for credit. They worked it out where they got the iPhone I wanted ordered and kept me in my current phone till it got there. And then, above and beyond, when that phone got there I came in and they sat with me for a couple HOURS showing me how to get all my pics and info transferred. I would have lost 8 years of pictures of my kids growing up if it weren’t for them. SUPER cool and patient customer service and I couldn’t be happier with how this whole change went, with their help!

Elizabeth helped get my husband and I on a plan. She was quick and straight to the point. No extra anything. Literally loved the whole experience. Liz deserves a raise or something. She dealt with a crazy busy store yet made the experience custom to our needs. 10/10 View on Google
