FNB Personal Loan Insurance is Pathetic

FNB personal loans was in contact with me after I got retrenched in January and I have sent through all supporting documents as I have personal insurance cover on my loan, which covers my premiums for 12 months and was told to that must do a review after 6months I did that and then they said send an affidavit through and then it will be extended to further 6months, I have comp**** with all there requirements and still they are debiting me. Then they that they said the want the letter of retrenchment from my company I did that and still no joy and what makes it worse is that you cannot reverse this debit for some odd reason. I am still currently unemployed and not earning a income but still they giving me the run around yet I have the insurance that covers me in this instance. This is absolutely unacceptable and I need urgent feedback and my debit to be reversed. FNB I AWAIT YOUR FEEDBACK.
