Thank you, Cynthia! Cynthia truly went above and beyond in helping me resolve my issue. For full disclosure I work at this Costco (not for TMobile), but I use to manage a cell phone store and I know a good employee when I see one, and that is Cynthia! In helping me transfer my phone from Verizon (btw, everyone on the team at the t-Mobile kiosk pitched in and helped so kudos to Cody and his staff), I emphasized what was important to me. She recognized why it was important to me and helped me, going above and beyond so that the transfer could be completed even though there could be potential complications. And sure enough the potential complication did arise, and Cynthia hung in there with me even after hours to make sure that it got resolved relieving an enormous amount of stress off of me. So thank you, Cynthia! And thank you to the Team at the T-Mobile kiosk at Costco Bradenton. Great job! View on Google

I owe Cynthia BIG TIME! I recently switched phone plans while abroad, and unfortunately, we ran into issue after issue trying to get my new SIM card working. I really depend on my number for work so I was super stressed. People usually throw the term “above and beyond” around, but I can’t think of a better way to express what she did! Even after her workday was over, she stayed in contact with me, and when she got home, we actually got on a call together and worked with tech support. We were on the phone for over an hour and didn’t finish until close to midnight! She took it as her personal mission and responsibility. She told me she wasn’t going to rest until it was solved and she absolutely delivered. Everything is working perfectly now! I’ve honestly never had someone go this far to help me. She was incredibly kind, patient, and determined. Absolutely blew me away! They are very fortunate to have someone like Cynthia on their team! View on Google

We were having trouble changing our phones over from Spectrum to TMobile. We had already bought the service so there was no potential sale for them. Both Marc and Cody were so helpful to us. They spent so much of their time to get our service and phones working correctly. They went above and beyond to help us View on Google
