Unlimited waiting period

My father past away and I'm the executor I've been to fnb to ask to transfer the money and close the account. They ask me to bring in death certificate and other documents I did so they submitted it then told me to wait 14 days.The days went by after the 14 days still no money in my account.I spoke to a consultant she spoke to someone over the phone that said the money will be in on Wednesday still no money so I went to the branch on Thursday the consultant spoke to a guy over the phone that said he can't give a timeframe of when the money will be in for me its unacceptable
