United Service Association for Health Care review: They say I owe them $234.00

As a result of losing my health insurance at work, I was looking for health coverage that would accept someone with what is considered 'pre existing conditions'. I was contacted by the company above, and they offered me a plan that was for $234.00 a month that seemed pretty good. However, you can't keep or see the doctors you want, and I sensed something fishy about it, so I canceled within the 10 day time period. Just yesterday, I get a BILL from them, stating I OWE THEM $234.00, when I canceled! they owe me $234.00, because I canceled in a timely fashion, and they have the nerve to do this? I'm getting the local media on this and heaven help them!
