Not in the fire service but ....
You need to find out what part of the physical you didn't pass so you can work on improving your results and nail the next one.
Be sure to remain respectful and not the angry young man you are understandably showing in your last few posts (trust me, I know how you're feeling, I've been out of work since being laid off 1 1/2 yrs ago other than a casual part-time job the past few months and the job search/interview process has been extremely frustrating). Perhaps there will be future opportunities with this department and you don't want to burn your bridges.
