membership cancellation

<p>I was approached by people from legal wise and persuaded to join, so I gave them my details and left. Today I receive an SMS informing me that there's money that will be deducted in my account. How so because I didn't give my bank acc or sign any document? I was not even aware that I was member already. With that being said I would like to cancel my membership as I am a student and currently not working. I tried e-mail the legal wise but till today there's no response</p>
