False accusation...?????

I am writing concerning the false allegation received from one of the FnB investigator officers called (Mogane Boitumelo),It happened that my account was blocked by the Fnb saying I received an amount of money of R6,800 on the 2022/12/01, So i had to go through my account history just to know the person who sent me the money. I discovered that I never received such payment then I had to write back to the investigator to inform her about the mistake, and instead I identified the amount of money I received on that day which is R6,900, then she wrote me back and stated the same amount I just corrected her for and asked me to send her proof of transactions and the reason for the money, then I provide her all the necessary documents showing the transaction history between me and the person who sent me the money he bought coins from me on the platform called binance i provide her the history and receipt of the payment as well as the admin email sent to clear me from the situation and also provide her the customer care contact of Binance in order to be able to help her in her investigation and also sent her to the police Affidavit, I had to write to the person who bought the coins from me to explain what happened. Firstly she told me that she never reported my account, secondly she told me that his account was the one who was reported for receiving an amount of R135,000 so basically she was the one who was reported and what i don't understand is that among all the people this person traded with On the 1st I am the least among all the binance agents she traded with so when I interacted with other agents they made me believe that nothing happened to their account from the R135,000 She bought coins from other agents of R85,000 and R30,000 but their account never blocked so what concerns me is that my own account was blocked just because of R6,900 then after sending this investigator the proof of transaction she still refuses to communicate with me on what to do upon all the emails and calls made to her even when i reported this to fnb complained department they just said they will get back to me they haven't done that till now this is going to two month, and I need my account to be unblocked because this is affecting my own business, I can't do anything. All my money has been blocked because of R6,900. This holiday time. I can't even buy my kids christmas gifts due to this, If fnb fails to do their own investigation very well before taking a decision on a foreigner account because clearly here among all the agents i am the only one who is foreigner so basically they believe Foreigners can't do legit business and this has been happening a lot these days. If I can't use my account to do business without being blocked or falsely accused by fnb I would love to get all my money and close the account. I can't be dealing with this all the time for the fact that I make sure I never received payment from a third party. I made sure I only traded with verified members on binace who already have their KYC verified to avoid this kind of situation. as well this makes it difficult for a ******* to trade on the platform.
