AA puts other people on your account and dont cancel your policy when you ask them too

I found out that the AA messed up with my account, I logged into my *** account and saw that on my name there was a different person attached to it I asked to get the person removed as I have no idea who this person is... I decided i do not trust them anymore sharing other people and my details with other people and I cancelled , I was on the phone and cancelled it and yet they still deducted this month ... i want to be rembursed and the policy CANCELLED
