Unprofessional Service - resulting in double deductions

Let's be honest, in the time of covid and lockdown, finances have become a bit tighter. So, now more than ever, the sentiment "don't mess with my money" stands stronger than before!!

Having said that I am SO dissappointed with FNB! I recently changed jobs, and informed FNB timeously to please move my debit order dates for their products to be deducted from my account. Side note: the app has been USELESS for the personal loan division, I had to contact them directly. I emailed, and subsequently called. The lady on the phone assisted me in changed my debit order dates from the 25/26th of the month to the 1st of the new month with my salary moving from 25th to end of month. She even told me because of the tight timeline the amount will increase slightly.

I was then notified on the 25th/26th that the deductions went off my account. Now concerned that a deduction will still go off on the 1st I messaged on the APP, with no assistance to my query.

I then called the personal loan department today and was told that the deduction will go off on the 1st again. WHO CAN AFFORD A DOUBLE DEDUCTION. AND WHY WILL I BE PENALISED FOR THE BANK ILL-INFORMING ME!!!

THis is ridiculous, the lady today advised that the lady who helped me should have informed me that it was too late in the month to change. And B, I was told that it can not be reversed. Why must I be penalised for someone working in this industry and with my bank who SHOULD BE APPROPRIATELY advising me for not doing their job.

I then asked to log a complaint. The consultant said she escalated to her supervisor. And asked me to call back in the week.

WHY MUST I CALL BACK FOR MY BANKS ERROR!!????
