I've been a customer since the Sprint days, well before the merger with T-Mobile, and I've been with the company for over 8 years. Augusta has consistently provided outstanding customer service every time I've worked with her. She is patient, kind, and always goes above and beyond to make sure I'm happy and that all of my questions are answered. She takes the time to explain everything clearly and never makes me feel rushed. I always leave the store completely satisfied because she genuinely cares about her customers. I recommend Augusta to anyone who uses T-Mobile. She is a true asset to the company, and her exceptional service is one of the reasons I've remained a loyal customer for so many years. View on Google

I had a wonderful experience with Augusta! She was incredibly kind, patient, and took the time to help me choose an updated phone. I'm not very tech-savvy, but she explained all the different features of my new phone in a way that was easy to understand. She made sure I felt comfortable using it before I left, and I never felt rushed. Her customer service was truly excellent, and I really appreciate the time and care she gave me. Thank you, Augusta, for making the whole experience so easy and enjoyable! View on Google
