Incorrect voucher details and funeral plan debit order

On the 4th of April 2025, I bought a Blu voucher on my African Bank app, but when I loaded it, it was marked as invalid on the Betway platform. I sent numerous emails to African Bank for assistance, and they would call me, but their consultants couldn't help for some reason, so I gave up. I contacted Blu voucher, and they said African Bank should give me the reference number of that voucher, but they didn't. I want those funds reversed to my account, or they must give me another voucher. I also had cancelled my funeral plan policy with African Bank because of the number of complaints I had that always went unresolved. I wrote an email to cancel the policy, and they still debited my account. I need those funds reversed also.
