Poor Service from FNB

I disputed 3 debit orders on 2 July 2020 via money assist and was promised feedback, which feedback was never received. I since managed to identify 1 debit order as authorized as I did my own investigation as I was not receiving feedback from FNB. I submitted a complaint via the FNB app on Thursday last week and was promised feedback within 24 - 48 hours. I just feel that it is so unfair that I had to wait for over 2 months for unauthorized debits which totals R1500.00. the amount differs every month and the reference remains the same. I am really dissapointed with FNB!!!
