I got it all sorted out after a coupe hours on the phone with T-Mobile. Go figure the uneducated store employee had no idea what he was doing. I swear I have yet to meet a store employee that knew anything at all. I hate when I'm required to depend on those idiots to "help" me. I've spent more than 7 hours in a t-mobile store in the last year waiting on clueless people to help me.
They never actually set my new watch up on the old watch line, so my galaxy watch wasn't actually on a phone line, just by itself. I wish they paid those guys better, I would have a new job. Something I actually enjoy too.
