Furious customer

I'm very disappointed with FNB. I went to open a case against someone who ****med me. At the police station they told me that they need a bank statement showing the amount that I've paid over to that person with the bank's stamp on it. Only to be told by the bank that I can't have one, I have to get one from the person who will be appointed to my case on MONDAY only. This is really ridiculous!!! By the time I get that statement the person would be long gone with my money. With other banks they don't have to wait for a month to get a statement, they can go immediately onto their app and get it instantly and their banking fees isn't even that ridiculous as ours. It makes me wonder, what do I actually pay for??? Please look into this in order for us to generate the statements ourselves with the stamp on it. This is really unacceptable or then there must be someone on standby over weekends. As it stands, I can't open a case!!!
