After my experience with Keyth, I genuinely felt like he deserved the recognition. From the moment I walked in, he was incredibly welcoming, professional, and attentive. He took the time to actually listen to what I needed instead of rushing through the process, and he made sure I understood everything every step of the way. What really stood out to me was how knowledgeable and dedicated he was. Even when something took a little extra time to figure out, Keyth remained patient and determined to find the best solution rather than taking the easy way out. He went above and beyond to make sure everything was taken care of correctly, and you could tell he genuinely cared about giving me the best experience possible. He’s the kind of worker who makes you feel like you’re being helped by someone who truly enjoys what they do. His work ethic, patience, communication, and willingness to go the extra mile really stood out to me. If you ever have the opportunity to work with Keyth, I highly recommend him. You can tell he takes a lot of pride in his work, and that level of customer service is honestly rare. Huge thank you to Keyth for making what could have been a stressful experience feel completely effortless! View on Google

5+ stars!!! If I could rate this store above 5 stars I would because the service is beyond excellent! I went to see if I could get a better phone with a camera that zooms out, I spoke with John Andrew who referred me to this store when I got there I was greeted by Keith who was so pleasant. Nemesis was so friendly she even took a selfie with me to test out the new lens on my phone. Tarun the manager was so amazing he took care of me, my brother and my dad!! We all got the latest phones and he gave us the BEST DEAL!! If you need a new phone go see this crew! Nothing but the best and you won’t regret it!!! Thank you all I will def be returning and referring more people to this store!!! View on Google
