unagreed services

This company is giving false advertising. They are tricking people into giving banking details for a loan but when you agree to the terms and conditions which is for a loan then they enter you into an agreement for financial advise. I did not qualify for a loan and I did not fill in any papers but they started debiting my account. I'm not rich. I have a family to support. This is *****. I need help they take 450 a month o advised them I do not want the service and the are handing me over for something I did not agree to or wanted. They trap the people and I believe I am not the first one. I hardly make ends meat and they do this to the people who are hardly surviving . I'm the only bread winner. ThatThat one they tale I need to buy my baby milk and diapers. I need help to take this further I want to sue them. Please anyone help.
