Clientele life debited money from my bank account without my agreement

I met one of the clientele consultants at a shopping mall so he advertised the policy insurance to me and he asked for my details as a proof that he spoke to me about the clientele policy. He told me that he is not opening a policy for me but one of the consultants will call me and ask if I want to join the policy or not on the same day but they never called. What broke my heart was to see a bank alert on the 23rd of October 2021 money was debited from my bank account with a reference stated clientele life. I was very disappointed because I'm not working I'm still a student I never agreed with any of this. So all I want is for clientele to cancel the policy for me and refund me.
