Email button broke, Sprint won't replace in-store

[djheir]

My Email button (top left button) broke off a few weeks ago and I finally decided to take it in to sprint Friday. They told me that this is considered physical damage and that I'd have to pay the $50 deductable and go through Asurian. Here's my question though, in the pamphlet that they gave me about TEP, it states that "wear and tear" are covered in-store. Shouldn't this be considered wear & tear since I did nothing to break the button and it just fell off one day? I also ran into a coworker at my job who's exact same button fell off and he didn't know how it happened.
