I Got Ripped Off My Job Didn't Pay Me

I took a job during the month of February and I have been working full- time for this company ever since. I was promised a salary of $4,000 a month. The pay would be commissions on the 15th and the salary would be $4,000 on the 30th of the month. I have not received any pay from this company since and today is April 11th. I left my full-time job to sign on with this company. I am the sole earner in my household. My husband is disabled and unable to work. We have been given the runaround of promises that the check was in the mail but never arrives. Today we find out we will not be getting paid at all!!! So here we are with no money to pay our bills, eat, or pay our rent. Any and all help will be appreciated. I have no money and no dignity left since working for a company that will not pay their hard working employees. Please Help!
