I want my money

On the 14/01/25 Capitec bank sent me an email stating that my account was recently identified as being involved in suspected *****. Funds related to suspected ***** were transferred into my account. These funds will be placed on hold, and you may be restricted from using your account until we complete our ***** investigation. These they are talking about are from my business account from another bank. I've being using my business account to transfer funds to my Capitec account prior and there was no issue. I want my money back and I want this account to be closed. I don't want anything to do with bank anymore. They said the funds were held due to a ***** alert from another bank. I asked them to send me the communication from that bank...they couldn't. Their account is working just fine hence they said I won't be able to use it. I don't understand what's going on.
