How can i make sure usmc recriuter is me the truth ?

i am in USMC dep and when under open contract because i was told i could get my job in dep. Well my recruiter told me i have motor t and i never picked it and don't want it. I told him i want to switch he said it is fine. But he keeps telling me not to worry about it and hell get me somthing eles. How can i make sure he changed it before i go to meps to ship ?
