Reversals of payment

Fnb has lost its plot,pathetic service and no sense of accountability .I wanted to reverse the amount paid via FNB app to the incorrect account. I went to Irene branch which is my branch.After waiting on the queue for more than an hour they advised that I must call a number which they say they can't trace the amount despite providing a bank statement that shows that the transaction went through.

I am so disappointed in bank and the service these days..

40 days later after Hello Peter they send me a message saying reversal unsuccessful
