Platinum Life preying on varsity students

These people are forceful. I told them I don’t want their policy because I’m a student and can not afford. Please note they called me 2 years back when I was doing first year in varsity and I naively gave them my banking details they said they would not take anything from my account until I agreed to the policy, so they have my banking details. I found out as soon as they hang up it means you agreed to the policy, my parents helped me out of it. Now 2 year later they call me again. The sales rep went on to tell me she just needs to tell me about the changes. I was nice enough to let her go on and I still maintained I will not take the policy I can’t afford it. I let her talk and now I received a package with the policy saying it’s active and will start charging on 1st April 2020. I’ve asked them to cancel that policy on 19th March when I received it, they are delaying the process (obviously to reach the effective date). Platinum Life is preying on students who are naive and don’t understand how these things work.
