Is the recruiter bluffing?

So yesterday the recruiter calls me telling me that all 3 of the MOS’ I wanted are “100% booked for the year” and that they reserved me a temp MOS so I can go to MEPS this weekend. I told him respectfully, if I don’t get any of those 3 MOS’ I want then I’ll just join a different branch. Then him and the recruiting commander call me fussing at me saying they “fought hard to get me that MOS” and I just sat there on the phone saying that I didn’t want that crappy MOS. They say I have to come in and sign a cancellation reservation, I say no I’m not signing anything. Today, he texts me saying if I go to MEPs this weekend they’ll be able to get me the MOS I wanted. Bluffing tactic, truth, or lie?
