FNB failing to reverse funds transferred to incorrect recipient and poor customer service

I've transferred funds through my FNB account via their Transfer to cell option and accidently paid into incorrect cell number. After realising my error I've made immediate contact with FNB via their chat and call centre options(Worst service ever, was transferred from pillar to post, and was met with rude and arrogant agents) as I just wanted my money reversed. I've even made contact with the recipient who confirmed that he was surprised when he received payment notification and also attempted to make contact with FNB Chat to have the funds send back if its sent by error. One of the agents eventually sent me the reversal form @+- 9am. ( Which ended up to be incorrect form, discovered by Team leader when they've called me back at 15:35). I've completed form immediately after receiving it, and no feedback ever since. No sense of urgency. I've even agreed to pay admin fee of a ridiculous R325. I don’t know how I will go through this month.
