It ***** man. I went through it with my insurance as well. My X-ray bill responsibility was close to $400. I received another bill or two later like you and it pissed me off. I called my insurance and demanded to know how long I was gonna get shafted. Naturally she talked a lot and told me nothing. I really do not like being involved with insurance companies and the racket they run.
You guys are lucky she isn't hurt so bad that she had to be hospitalized. Sometimes I guess you have to count your blessings.
