Hey josuedg! Welcome to T-Mobile - we're so happy you chose to switch, I know making changes after such a long period of time can be disorienting - but we're stoked to have you here and hopefully we'll do a great job of making this an easy change! That said, I am sorry to read about this unfortunate first impression. Telling you about "the hook-up" after the fact seems unnecessary (and maybe a little uncool).
Every employee has a limited number of codes to pass out; and we're all out here on Support. However, it's worth leaving the post here in case someone pops by who still has a code to give (we're still seeing that happen here and there); so we'll leave it open for a bit with fingers crossed for you! I would love to get a little more information about the situation you mentioned in your original post, though, if you don't mind, so that we can make sure to do better next time. I'm going to send you a PM, which you can check and reply to in your inbox. Thank you!
