Commission Only Legality

I was hired by a company in CA as a commission only sales rep. I reported to an office, had a set schedule, was accountable for a certain number of outbound calls/day and harassed endlessly about my production. I have previously made 6 figures in sales, but that's immaterial to my question: Is it legal to pay an inside sales rep commission only that fell UNDER the minimum wage threshold. The paychecks were processed as a regular employee with deductions, not 1099 (though I think they'd have a hard time trying that route anyway). I worked through my lunches, 9a-7p at the office and then an additional amount of hours late into every evening (sometimes until 3am) and full-time over the weekends. I quit when they started really jacking me around over new business I generated from Australia and they wanted me to prove it was from my (web) efforts. I then asked them for the "alternate" version of the sales contract which offered $9/hr (I have a copy of it but it's not signed) They said they'd check to see and never called me back... That can't have been legal right? Some advice would be great. A referral to a competent attorney in Los Angeles would be even better! This is the first of TWO jobs playing this game with me this year... I know the economy is bad.. But come on! Help! Thank you! :)
