What recourse do I have in regards to suing this company?

Nothing much you can do. Beware of any Attorney who would take this case because this would cost you Tens of Thousands of Dollars.
There really isn't much you can do. It doesn't sound like you have grounds to Sue them. If you are an Independent Associate for MCA, how did you come to by this?
You didn't say if you had actually made any sales for MCA, if you did and are not getting paid, there is a reason why. It's sounds plausible to me that you that you are being misled.
This could be a scam by someone getting leads from you and they're legally able to market and sell MCA and are getting paid. Do you have proof that you are legally able to promote and try to market make sales and get paid and how much?
