Disgustedly disappointed and upset to the point that I want to close all my accounts that i have with FNB and move to another bank

I am so disgustingly upset by the customer experience I have been experiencing since yesterday by fnb. I went to deposit money at an FNB atm in Kolonnade yesterday around 5, but when I was busy the transaction was canceled and it neither gave me back the money. It was an R5400 to be precise. When I called the customer care and they asked be to check if the branch is still open, which was not, then she said she will send me a form that I need to fill in and return it back and it will take 5 days to resolve which I am very unhappy about because this money is urgently needed for easter. I have completed the form and sent it back together with the receipt from the atm and received a confirmation email from the card and cheque dispute department. I was worried by the confirmation email because this is an atm cash deposit dispute, so I phoned it this morning and spoke to four consultants in the dispute department, who said they are not the relevant department, spoke to one in the ***** department. To now I have no one who can help me with my dispute and I am soo worried because R5400 is alot of money, that i cannot afford to loose.
