Frustrated and disappointed

Im very disappointed with the service I got from fnb the Grove mall, I transferred funds from my *** account last month on the 27th of September to a closed loan account in fnb by mistake. I have been on calls with consultants at fnb for refund. Ended up Goin to the branch at the Grove mall I was assisted by Ntumeseng whom later slated this querie to her team leader Luyanda but to my surprise this refund is always taking 24-48 hours but nothing is paid. They only do follow up when I visit the branch and I go the fnb the Grove every 2nd or 3rd day till the 27th of September. This is really frustrating I've a consultant myself I know how tiha is done but I feel like they not doing anything for the refund to be done only follow up when I'm at the branch
