Hi so, I am a t-mobile customer for the moment and i ordered my evo through student discount yesterday knowing i would get 15% off my bill each month. however, i was reading some stuff online where they say sprint customer service is horrible as they frequently 'go back on promises and don't give customers the discount they promised on bills'. is this true? i LOVE the evo as much as the next person, but if this is true than im going to take my phone back once i get it (next week i think) and go back to t-mobile. can anyone tell me if this is true or sounds familiar? THANKS!
