FNB failing to make correction on the account and reverse the funds to the sender

I have incorrectly received funds in to my account but my bank is failing to reverse the funds to the recipient and make correction on the account as my account was overdrawn to my attention and experience is correction can be done on the account and transaction can be reversed on the account .

this is the second time this kind of matter is taking place while the bank end support it is failing to assist me . 1st incident they have only managed to assist after posting a bad review on Hello Peter , why would we have to post bad reviews always for us to be noticed and taken serious and be assisted .

I would recommend all back end support staff members to get a proper training as this is reflecting as *********** staff including Team Leaders and Managers .
