Clientele life sales representatives misrepresenting their services

I was recently ******* by a clientele sales person to join the client funeral plan. The lady said we only checking if I qualify for the policy and that I'll be soon contacted by clientele to tell me more about the policy and to confirm if I'm interested, but to my surprise a week later I recieved an sms from clientele informing me that I should make sure that my account got enough money this December so that they can debit some money from my account. I don't have any money and am a student, am afraid that they will debit the money my parents sent to me for school things and grocery. Can you please cancel the policy before it starts taking my money. I can't afford it. I don't even know which policy is it exactly. I really want it to be cancelled
