Sprint is so evil. They bait user with lower fees then change the rate during the contract period (yeah, I known, they hide behind their agreement stated they can change the term). They shouldn't even call this a contract.
Image you rent a call for a week and during the middle of the week, the rental car company called and say they are raising your contracted rate by 50% because it's stated in the contract that allow them to change the rate.
Truly evil company
