I can't help but notice that you've been with us for almost/over --- years beginning with Sprint (pag from magenta complete ung cx )! I'd like to take this opportunity and ask, how are you with T-Mobile so far? (Send before recap, to check if possible promoter!)

"I am really glad you shared with us your thoughts about T-Mobile! We hope our service and work brought a smile to your face and made your life just a little easier. 

Please let us know if there’s anything else we can help you with. I just want to make sure that I did not miss anything for you today."  (IF YOU SENT "HOW ARE YOU WITH T-MOBILE SO FAR" AND CX FEEDBACK TO T-MO IS VERY SATISFIED)
