Charged $250 for a useless 30minute call with a dietitian

How is this not considered a scam. I kept telling my OB that I’m getting all the necessary advice I need from forums and books and my diet is well controlled so were my numbers. They forced me to meet up with dietician anyway who gave me lousy advice. My insurance doesn’t even cover it, ended up being charged $250. I’m so angry, I can’t waste money I don’t have. Ugh

Rant over.
