Disappointing service from my bank FNB

I have been a client for years now , i transferred money to a credit card account that is closed by mistake.

I asked FNB to assist reverse the transaction , i am being sent from pillar to post from 25 November , how long does it take to reverse a transaction?

i spoke to the below staff members on the chat platform and it looks like they all received different training on how to resolve queries or assist their clients.

25 November i spoke Jason and Baatseba, 28 November i spoke to Tebello and Annalise, 13 December i spoke to Sherminor and Natalia, 21 December i spoke to Michelle and today 24 December i spoke Baatseba again still no assistance.
