my account had been stopped for 3 months

Good day, I am writing to complain about my business account that had stopped since the 10th February 2025. I called the ***** line and was told a client who deposited the sum of R300,000 on 29th October 2024 reported. I was then advised to contact transactional******** and also ********. I have contacted them since February and till this date i have not gotten any feedback. On one occasion speaking with a consultant from the ***** department, I was asked to send an affidavit explaining the reason for the funds received, i have sent that affidavit since the 7th of April and till this date I am still yet to receive any feedback regarding that affidavit. I have long reached out to my client of which we resolved amicable and she also contacted standard bank last week informing the ***** consultants that we have resolved out issues as she also told them that she authorized the payment of the 29th October 2024 and that they unblock my account but still no response till this day and moment. I am running a business and do have funds belonging to other clients that I cannot access or be able to deliver on the services I have been contracted for. This is really frustrating and getting out of hand on my side as clients are threatening to sue me. my client banks with standard bank as such it would not be a problem getting hold of her to confirm this funds despite she also called last week regarding this matter. Please see to my complaints and resolve this matter ASAP or else i will be forced to involve my lawyers as i have waited for over 90 days. Thanks and kind regardsAyanda Fuwani
