This is a case where I would have asked for a Supervisor because OP was clearly in the right and there was no grey area. It also is nice educating that agent to then lift DL's communal agent standards.

I HUCA if there is a grey area...like the former SDCs from F to domestic D1...but this would have been resolved with either referencing the CoC to Agent #1 or asking for Supervisor or Reissue Desk.

Giving the dumb agent a 1 also helps because they shouldn't be so uneducated.
