Disgusted by the lack of service

My FNB private wealth account has been put on hold by FNB ***** since just after 8pm on the 25th of August 2025. I was not notified by FNB on this hold and realised it when I could not make any payment on the morning of the 26th of August, I then contacted the messaging service on my banking app and was then informed that I needed to contact ***** division as my account is on hold . I proceeded to do that by 8am and was told that there is no case number on the system just a hold and the person from FNB ***** who can give me more information is Stella and she is night shift and will only be back after 2pm . I then proceeded to call my private banker and was told that only ***** division can assist, I called again to speak to a team leader who can assist in at least telling me the reason for the hold. I was then told by another agent from ***** division that she cannot provide any information as there is no case number or update on the case and that an investigator will contact me before 5pm today. I then waited until after 2 to call Stella and was told that she only comes in at 3 and to call after 3. When I called after 3 , Stella informed me that it was due to money that was transferred to my account from a capitec account on the 24th of July 2025, I had sold a vehicle and this transfer was in payment for that vehicle. I was also told the investigator will contact me. I then called back just after 5pm and was told that the investigators only work from 8am to 5pm and I must call back tomorrow. This is absolutely pathetic service from FNB and seeing that I pay almost R2000 in bank charges and service fees. Where is the customer service. As soon as this is resolved I will be changing banks. It is month end and I cannot access my account to do any payments and will soon have people that need to be paid screaming at me for unpaid bills due to an *********** bank. Where is the investigation first before putting a hold on their customers account.
