Lack of professionalism

I took my daughter to ER because she had limp which wasn't going away. The doctor was brief in examining my daughter and told me to come back after a week if it got worse(mind you, she had already been limping for weeks now). I then decided to take her to another doctor who found a problem on her hip. (This is where the problem starts) I brought this to the hospitals(Union) attention and how I generally wasn't happy with the service I recieved but they just simply referred me to the docotors(DRS MONTEITH NAY WELLS AND HEYMAN INC). The doctors then got one of their representatives to send me an email telling how my concerns had been noted and that it will help improve their service next time - for other people. I emailed Union hospital again seeking advise and steps as to how to go about it if I was not satisfied with the outcome. Union once again forwarded my email to the doctors again who got another one of their representatives, this time more aggressive, to mediate. This lady, being a representative of the doctors ofcourse, argued with me about what the doctor did, what the doctor said to me and even took it as far as telling me, the father, that my daughter's limp was getting better, bearing in mind I've only been there once for the limp. This lady ended up telling me I must do what I want to do. The hospital manger hasn't intervened, the doctor in question hasn't bothered talking to me about this, instead they get an assault weapon(Mrs/Ms.. .) to handle my grievances.
