FNB Refusing to refund Client

I bank with FNB it's been less than 3 months. I then decided to take up their funeral policy which I then decided to cancel the one due to the people I was covering were already covered. They cancelled the policy and refunded me the two premiums I had already paid. This was in Dec then in Dec as well on the 27th they tried taking my money for the same policy that was cancelled which created charges of 210 they refunded that without me doing anything. Funny enough on the 5th of Jan 2024 they took money for the cancelled policy as well as another payment for the policy I am keeping even though it was already paid. Now when I am asking for my money back I am told that they can not see the debit order another agent said they can not do reversals on FNB debits then it was I need to speak with the insurance team the insurance team says I need to speak with the debit team and I was asked for my bank statement from the bank that I use disputing a policy that I have with them but I have to send them a statement. Pathetic service to the say the least. I do not even want to know how the service is when one has to claim. I want my money that was taken by you guys and I don't want to be told any stories. Already you guys have fees till kingdom come and now to find you are ******* as well wow.
