Unreasonable Account Freezing

Standard Bank has frozen my bank account for no reason. I have submitted an affidavit to them confirming the reason for receiving funds into my account. Despite the person that paid money into my account sending them countless emails and affidavit to confirm that they made the transactions, they have refused to unfreeze the bank accounts. This is very annoying and frustrating. If you don’t want me to bank with you release my money and shut the account down
