FNB- Terrible Customer service by Managers

I have made a request to FNB regarding one of my accounts in September. After multiple phone calls, and visiting the branch I received the email address of the managers Megan de Kock, who referred me to Kelly Minnaar who referred me to Lebogang Mochemi. None of them could help me with the request instead they closed the wrong account of which was linked to debit orders. It is now December and after visiting another branch to try to get help/support they also phoned another manager whose address was given to me incorrectly. I went to Capitec to ask if this problem is something they would be able to assist me with and they immediately came with support and assistance. FNB Could you please respond to my request.
