Cancelation of Policy problem

I took a policy in December 2024 and when the quotation was done I told the person who was helping me with the policy that I can't afford the premium they must cancel it. I even phoned Assupol on the 18th of December requesting them to cancel the policy and I was told that it was canceled. I went to an Assupol branch in Ulundi to verify if it was really canceled and they told me that it has been stopped. To my surprise on the 15th of January Assupol debited on my payslip. I went to the branch to enquire about that and I was told that it was late when I canceled it was processed already and I understood. Today I received my payslip and the Assupol policy is still there they are still going to debit on the 15th of February again. I don't know what to do anymore because i was told that it was canceled in December when I phoned but they keep on debiting the premium.
