Debit order for unknown life policy

I met a clientele agent last month who told me about clientele perks and got me registered for it. All of a sudden I received a bank notification about a clientele debit order that was deducted on my account on 22 & 23 April for a life policy which I didn't take and have no idea about. This annoys me a lot because they charged me R500 in total yet I have no policy documents and they have never asked for any documents from me before activating the policy and I have no idea who the beneficiary is....how on earth are they able to activate a policy without having any papers from me also deduct money without notifying me about the policy. I have never received any form of communication from them...no phone call, no sms, no email yet they took my money and have the guards to tell me that it is non-refundable. Their agents have no idea at all of what they are doing. I have told them to cancel everything and I want my money back or else I am taking this matter to the police. I am going to open a ***** case agaist clientele because they have absolutely zero rights to deduct money from my account for a policy I didn't even receive any documents for. This is bad service and I'm so angry right now.
