Wage reporting when hours change weekly after 5 years as a hotel front-desk agent

I work some days through a staffing agency while still certifying. It has been a long 8 weeks. Sometimes my paycheck is late by a week. Did anyone get an overpayment notice from a mistake?

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.
