I call and talk to the Loyality dept..whatever its called...ive been with tmo since they were Powertel so whenever they made switch to tmo ive been there. Im always polite, start off by saying ive been tmo a very long time...im a loyal customer as you can see and i love your service. Im interested in (whatever phone you want) what special rate can u offer me? Over the years ive had upgrades awarded early, premium discounts..etc. I dont really think its what you say, i just think its how you say it. Be polite, show respect..if you have to bull**** it, then bull**** it. You gotta be an actor...tell how much you love them and they will reward you. If you go into it being an asshole you wont get squat. You gotta play the game to get what you want. But being rude etc, will never reward you if you are trying to benefit yourself.
