Call them on a Monday morning first thing before they get too busy. Also if you live in a city where they have an office and if you have the ability go to the government office in person.

Of course you could bluff your employer, tell him you've contacted the labour board and they've informed you that he has to pay you all the monies owed to you. You're being a nice guy giving him a chance to straighten it out now before you send the labour board after him.
