Refund from Metropolitan for deducting the premiums of the policy that i have cancelled.

My wife decided to cancelled her policy with Metropolitan earlier this year 2022. She was paying the premium of R 1723.00. She then got a call from the consultant (field worker) from Mertropolitan who sold her the policy where by asked her with disapointment that why did she decide to cancel the policy and then my wife had to explain herslef to her which was also uncalled for. Then during the month of March and April the premiums were deducted which means we were ****** an amount of R 3446.00. Then she called the insurance demanding that they should reverse that money because as far sa we know we are no longer their clients, and they said that we should submit the following documents, 3 months bank statement, Affidavit and copy of the Identity document then they told us that they are going to investigate it and get back to her. As I write this she has just made a call and she was told that "the matter is still investigated", and the chance is that there is a deduction of premium for the month of May. This to me is a crime, because someone has all my details it does not mean that they can restart the policy that i have cancelled... If I get my money back I am prepared to take this matter further.
