FNB app magically changes important info!!

On the 1st of Dec 2021 I transferred my domestic worker's salary using the FNB app like I've been doing for years. She is saved as a beneficiary which makes things quick and easy. She banks with Tyme bank and it takes 2-3 working days for the money to clear. When she arrived at work on Mon 6 Dec, she informed me that her salaray was not in her account!! I have never had issues with transferring her salary so I went into the app to investigate.

I discovered shockingly that her OLD bank details had magically appeared in her SAVED beneficiary details. I could not believe this because I had DELETED her old banking details!! She has had a new account for months and I have been making transfers every month without any problems. I did NOT change any of her details!!

I contacted the call centre this morn 7 Dec only to be told that I must complete the payment reversal forms. The terms and conditions stipulate that there is no guarantee that FNB will reverse those funds and that I have to pay R325.50 Irrespective of the outcome of the investigation.

So let me make this clear FNB, THIS WAS NOT MY FAULT. I did not change her details. I want an explanation on how this happened and I want that money back!!
