Cancellation of the Policy and Refund

I do not Understand why taking money from our account without our permission. I sent an email declaring the cancellation of the policy and asking for a refund. even today i have not get any response. I am a student, i cannot pay for subscription. The guy who approached me **** to me that i will get paid if i join IFA and nothing will be required from me. now he is no where to be found and clientele is taking money from my account. Please cancel the policy and refund the money i paid because i had no knowledge of what the policy was for.
