Shout out to Joseph at this location! He spent two different occasions with me helping me out with a chaotic situation with my plan and was so kind, didn’t rush me, and truly wanted to help. He didn’t try to over charge me for things I didn’t need and was just overall a great employee/ person. If you ever need to go into T-Mobile ask for him and he will take care of you! View on Google

Stephanie provided exceptional customer service! I visited this T-Mobile store to return my T-Mobile Internet equipment because, unfortunately, the service wasn't meeting my needs. Zoom meetings would constantly cut in and out. I often had to turn my camera off just to get through calls, and the connection seemed to get even worse on windy days. Despite my frustration with the service itself, Stephanie made the entire return and cancellation process incredibly easy. She was patient, knowledgeable, thorough, and took the time to answer my questions and ensure everything was handled correctly. What really stood out, though, was the care she took when applying a new screen protector to my daughter's iPhone 17. I was genuinely amazed watching her work. She applied it perfectly and took her time to make sure it was done right. It's rare to see that level of attention to detail and pride in customer service. I've visited several T-Mobile stores over the years, and I would absolutely make the trip across San Francisco to this location again just to work with Stephanie. She made what could have been a frustrating errand a genuinely positive experience. Thank you, Stephanie, for your patience, professionalism, and exceptional customer care! View on Google
