Funds paid to an incorrect/non existent account at FNB

I incorrectly paid money to an FNB account in late May and early June. It was completely my fault but I registered a complaint in early June. It is now coming up to 3 months with no written feedback or updates since the issue was first reported. I would have thought that money paid to a non-existent account should be rejected. FNB are a compete waste time from my multiple attempts for them to do something about it.

The money must be in limbo somewhere so it is hard to comprehend why it is so difficult to resolve. The Capitec staff are always friendly and sound willing but nothing is advancing at all. Please help!

They have all the information from our numerous discussions.
