It sounds like they only paid you for a few days of per diem. Maybe they didn't pay you for your time in Miramar but they did for the time in Miami or vice versa. I don't know what your base is but if its FLL maybe they didn't pay you for your time in Miramar, saying it was in base so you didn't qualify for it.....total bs but just throwing out ideas. Give payroll a call and ask maybe they just made a mistake.
