Reverse my money and cancel policy as requested

I joined the life policy through ifa. A month later I tried to call and made that call me back thing. And they did call me and i told the guy that i want to cancel my policy he told me to wait and after sometime and tried to persuade me to keep the policy I told him I couldn't afford the policy am a student don't have such money to be debited from my account every month he told me his gonna give me time to think about although I told him I don't wanna think about it i just wanna cancel. A week later someone different call and told them as well I want to cancel the plan then they told me they gonna cancel it but clearly they didn't. Today I was sent money to go buy one of my textbook only to find out clientele took all of it 293 ×2 which is R586. Would you guys please refund my money I need it . There was a reason why i cancelled it in the first place. Don't let suffer because of you
