FNB Digital Banking and branches provides poor service.

I am trying to pay one of my beneficiaries, ABSA, whom I pay monthly via EFT. Now I cannot, I visited the Mall@Reds branch and we tried in the bank without success. The banking app on my phone indicates it is successful and will reflect later, nothing happens. Then I tried the internet various times. It sends a approval request to my phone app, I approve it it it shows it is successful, however, returning to the laptop it gives an E99999 error. After various calls to the Digital banking div and the referred me to a branch/teller. I am just from the branch in Pretoria and they also receive a error when trying to do it. From 15-18 Feb 19, nothing and I am charged interest , almost R300 per day on the personal loan I wish to pay. I assume I am going to get a lot of pay and clear cost from FNB for the transaction did not work. Poor Service.
