Inconsistent communication - Interviewer Issues and Answers Employee Review

I can literally ask sup 1, sup 2, and the manager the same question and on the same day, and get 3 utterly different responses or else only get responses that skirt aroudn the question rather than addressing my concerns. It's annoying when I am trying to improve my performance. It's infuriating when it messes with my paycheck. A big miscommunication is, when exactly can I get paid? The answer: "it depends." That isn't good enough.
