INCORRECTLY TRANSFERRED FUNDS

After calling Nedbank several times to please remove the my paid up credit from my internet banking profile. It was never done. Today I mistakenly transferred funds to the closed credit card and immediately phoned the call center to have the funds reversed back to my cheque as I am travelling. I was promised that's possible. Now at 3 pm the funds have not been reversed. I am told it is going to take 48hrs. Thanks to Nedbank weekend away plans gone. What could possibly be so difficult with reversing my money.
