I cancelled the policy 3 years ago

I was called about 3 years ago for a policy i took out the policy and realised afterward it was not a funeral policy but a accident policy i called and cancelled the policy. I spoke to the initiator of the policy Mr Naidoo snd asked him to cancell. He assured me it was cancelled. I recently discovered 3 years later thd policy was never cancelled and ive been paying R141 a month for the last 3 years i never received a statement or any notification the policy was still active i have been waitimg for them to retrieve the call that confirms i cancelled please refund me.
