FNB Covid Department Service Is Horrible

I took a Covid loan during the pandemic, and was handed over to Blake And Associates, and I have made arrangements to pay the minimal amounts every months. In March the 24th I called Blake to inform them that I will be settling the account on the 26th and asked them to stop the debit order of R400 that was suppose to go through on the 28th. I did settle the account as promised on the 26 of March but the debit order still went off on the 28th of March. When I called Blake to my surprise FNB couldn't allocate the amount that I have payed to the very same account number that I used to make payments previously. Every time when I call FNB I am being transferred to a different agent and have to relay my story over and over and send POP to all of them. Since the 26th of March 2024 to this day my issue is still not resolved. I made means of paying R4 655.15 to settle the account and FNB CLAIM that they cant find the amount but while I was paying 110 a months to the same account number they could allocate the payments. The customers service at FNB is HORRIBLE the agencies the don't have patient and rude. I called today ( 08/07/2024) and I spoke to the lady by the name of Petunia and I relay my story to her as well before the end of the call I asked her for a call ref number she told me that would be my account number. I'm asking if this will ever be resolved or I should just accept that I have been ****med by FNB.
