Sorry to read that you had this bad experience in our T-Mobile Shop. This is not the level of service we want to provide our customers!
Unfortunately there is no interaction concerning this matter, so I have no way of informing this colleague. Hopefully I can take away some, or perhaps even all, of your disappointment. I have sent you a private message with some more info.
If you have any further questions, don't hesitate to ask!
