Heard about T-Mobiles 14 day free trial for home internet and was excited because I’ve been dealing with a nightmare of service with brightspeed. Came In the first time and so so excited for the new internet! The so called “boss” of the store made everything so simple as far as signing up and was told “just go home and plug things in and you’re good to go.” I did so and oh my. What a not so good start! Connection errors, slow speeds all the way around. I thought to myself. “What a joke.” I come in 12 days later as I finally get a day off to deal with this and was greeted by.. *SAY IT LOUD FOR THE ONES IN THE BACK!!** MADI!!!!! I explain to her everything that happened and I was a little bit annoyed. She checks in… nothing was even set up properly by the so called “boss” of this store. Madi was swift, bubbly, educational and showed true knowledge and care not only for me but for another co-worker of hers.. why not have *MADI*! Run the store instead of this guy? I was told he has “a lot” to learn but when you’re at a place with not so good reviews already? Why not consider a change. Madi. If you read this. Keep being YOU! You’re absolutely incredible and your hard work and amazing personality will pay off! Thank you so much again!! I’m still waiting for that survey in my email!!! Yall check out MADI!!!!!!
