Ashley, Daphne, Mo, & Jorge were amazing at the Tmobil store in the Brass Mill Mall Waterbury!! I was having problems with no WiFi on a iPhone 12 I was trying to trade in. It needed to be reset to factory settings, apple tried resetting it and was unable to do so without a month of waiting for it to process! This wait would have cause me to no longer be eligible to trade in the phone because it was well past the trade in deadline. They all went above and beyond!!! They called customer service getting them to make an exception, got them to give me credit for the phone the way it was, notated my account and emailed me a shipping label! They really care about their customers and do whatever it takes! Thanks to this team I saved over two hundred dollars today! Thanks guys! View on Google
