B3 Funerals debiting twice and ignoring communication

I’ve had a funeral policy with B3 since 2019, early 2025 I contacted them to update my contact details. To my surprise from November I had two underwriters (RMA and Cliente) debit my account for the same policy. In January on the 9th I called B3 they said I should reverse the Clintele debit order which I did, they told me there was communication sent out that they’ve changed an underwriter, which I did not receive because they didn’t update my details. In Feb and March same thing happened two underwriters are debiting for same policy. B3 is telling me that they are with RMA and that Clientele continues to debit even though they moved from them. B3 asked me to called Clientele to cancel which I did, now B3 is telling me my policy payments are not up today. I’ve mailed their client service department three times with no response, I’ve included proof of each months debit orders that went out. Yet they still insist over a call (Zanele Mathebula) an agent that my policy is still outstanding payments from 2025 August.
