FNB are USELESS

I have never been so frustrated in my life. I have a covid loan which FNB have been deducting payment via Debit order for 5 years In April 2025 however FNB did not deduct the debit order. I then paid the amount manually as to not be a bad debt and logged a complaint with FNB as to why they stopped my debit order. Octavia assisted me and after explaining my problem she forwarded me a debt management link. I have never been so insulted. Then the the 06/05/2025 FNB went and deducted the debit order so now I had paid twice in one month. So I log an complain again and dispute the debit order as I had already paid and Mookga tells me if they reverse my debit order i will be in breach on contract and will receive interest and penalties. FNB you are useless. I WANT MY MONEY BACK IMMEDIATELY or I am going to the ombudsman.
