Some are really witches!
CALL, and speak to a supervisor, or another scheduler or person that works with that account (bank, store, etc..) You shouldn't have to 'eat' it. Sometimes I keep special bonus job emails until I get paid.. so if push comes to shove, I can say, "Well, I have the email you sent showing you would pay a bonus of xyz..."
Do NOT be rude, raise your voice, etc.. you'll just get a black mark by your name.
