Inattentive and indolent act of Debt Review

All my FNB credit products have been approved for Debt Review in 2019 whereby all relevant documents were submitted as the power of attorney to cancel all debit orders. All my debit orders have stopped since 2019 until the 25 January 2021 whereby one of my personal loans have debited my FNB cheque account with the default amount of R4544.74 and my debt review for this one product has been deactivated without any reason. I have called the Dept review department, which requested the power of attorney debit order cancellation form to reverse the debit order. My debt councillor and myself have sent the signed power of attorney debit order cancellation form several times and has questioned the deactivation but unfortunately, we have been ignored. I have been faithfully paying the full amount of expected debt, my history of payment can vouch of my payment record. I have complaint with FNB REF ***, but their response is non receipt of the debit order cancellation form, which is so frustrating that we have sent several times and should be on the system since 2019. On the 02.02.21, I phoned again Debt Review at 15:06pm and the consultant could not find our emails of the power of attorney and referred me to her team leader Mr Wonder Silinda. He responded on the 03.02.21 that an urgent refund will be actioned, and I can expect my funds 3-5 business day. Today is the 5th day and no funds in my bank account. My complaint to FNB Debt Review is their inconsiderate, lethargic and inability to solve a problem that has been caused internally effectively. I had to waste my airtime and my time trying to resolve this matter. I had to humiliate myself to borrow money and pawn my goods to have some food and transport money. Worst of all I am left without any funds to survive this month and must beg like a dog for the reversal of R4544.74. FNB Debt Review have exploited my patience and financial circumstances. How must I survive without my funds and why should I have to wait so long to be refunded????
