NO FEEDBACK ON UNAUTHORISED PAYMENTS ON MY ACCOUNT

I am a client of FNB and normally could not state enough how satisfied I am with all their services. But now, it makes me think twice. I noticed on my banking app and statements that a amount of R44.99 goes of from my account which I haven't agreed too. I sent a mail to the debit order department with all the screenshots of the payments which went of since October 2022 and requested it be investigate and the amounts which qualify for writing back, be reversed. For two months now, I have sent about 6 mails, receiving my automated replies, I made several calls with the promise that they have a turnaround time of 5 working days. I even went on my app and tried speak to consultants who advised me to send a mail.. And now, another start of November, with just another R44.99 deducted from my account... I wonder for how long I should wait. If this is the way how FNB cares for their clients, I really do not want to be a client anymore...
