 Just a thought,
Unless the person is at the counter of a store with ID how does sprint know that person really is said customer?
Answer:  they verify using same practice that all customer service agents use when you call on almost any account.  Name SSN Mothers maden name, address, phone number, secret password/PIN, ect.
It sounds like one employee at sprint dropped the ball on this one.  Myself I have two kids and only load them up at the same time, this isn't allways possible.  Personally I would definatly take sprint to court if I had paid extra for the "GPS tracker" and couldn't use it when I needed it the most.
