FNB does not allow us access to our own funds!

My elderly dad opened an fnb account, paid into the account was his retirement policy and my transfered her retirement funds into dads fnb account, we then get a message from fnb that the funds mum paid had been on "hold" due to verification, my parents were instructed to go to a police station for an affidavit, send all documents where payment came from, whst the fund are for and and and...its been over 48hours since the hold, dad's called fnb 2 times, no Manager available only thing we being told " we must wait" really? How much longer must they wait for their money?? The funds are needed for purchasing a property, which needs to be paid tomorrow 01/03/2023, all this has been explained to all the people since the "hold". The lack of care and urgency it pathetic! They can see the money being paid from the retirement! Sad part is, we convinced parents to move to FNB just for them to actually hate them at this point! The biggest mistake was opening this fnb account! We get into **** with the lawyer for the property purchase since FNB won't allow us access to our own money! We will take this further due to incompetence! No Manger available to help with escalation! Guys DO NO BANK with fnb or move to fnb u will regret it! At this point we want to close our business and personal accounts with fnb and move to nedbank, they actually care!
