Bima

Is Bima health insurance a scam? A week ago, I met a girl who stopped me and started talking about the benefits of paying. I paid and the next day, a man called me and started asking me questions, it was then that I got to know that they would be withdrawing money into my bank account automatically. I have tried cancelling the subscription but no matter what I do, it doesn't work. I am unable to get through to them too.
