A-freakin'-men to that. Assuming the absence of a union, chase it up the chain of command as far as you can by yourself, and if you keep getting the runaround despite have proof positive in hand, I personally would get that letter written from a lawyer.

Edited to add: since you aren't getting satisfaction from payroll, try HR. I'm sure someone there has enough knowledge of labor law to know this is a battle they don't want to fight.
