FNB ATM took my money

I had a despite with Fnb regarding the money I did not received. Then they send it to *****, I had to go and do affidavit. I am highly upset with this as I did not received my R3300,00 from the Atm. On the 7 February 2020 14:26 I did not received my money. I needed this money as I should had my paid my Ekurhuleni bill with this money so that they could reconnect my electricity. The hole weekend I did not have electricity because the Atm did not respond the money. And on this letter you tell me the client I **** about this transaction. How does this work. Can any body help me with this, it is costing me money to get my money back from Fnb. Petrol, airtime, data and my time of work. I want a answer today I will not wait another 7 to 14 days.
