I initially came into T-Mobile with two friends who were trading in their phones, and Sofia immediately demonstrated why she’s an outstanding manager. From the moment we arrived, she led with professionalism, respect, and genuine care for my friends’ concerns. She was highly knowledgeable, patient, and made sure every detail was handled correctly. While assisting them, Sofia also took the time to engage with me. I shared that I had previously been a T-Mobile customer and had a poor experience years ago. Instead of dismissing it, she listened attentively, apologised sincerely, and explained how much the company has evolved. She clearly and confidently walked me through the current promotions and the way T-Mobile is structured today. Her leadership, transparency, and customer-first approach left a strong impression on me. Because of her professionalism and the way she runs her store, I felt confident switching my service back to T-Mobile—this time with great perks and discounts that truly added value. Sofia G. sets the standard for what a great manager should be. She leads with integrity, cares deeply about her customers, and creates an experience that builds real trust. I highly recommend her and her store. Warmest Regards, JIMMY HO | CEO | JH HEALTH GROUP CORP View on Google
