Absa issues with late estate account

We have had a bad experience at Absa. Our father passed away two years ago so after having months and months of problems with his estate account we ended up having a problem again. GEPF paid money into his late estate account so when we wanted to get it they ask where the money come from and wanted proof it was from GEPF and so we phoned GEPF and they did confirm they sent it and all that. After all that they told us the account has to be closed and will take 30 days but when we went for a update it was said the person at the bank never summited our case by that time it was almost 30days so we had to wait all over again. This week we will be reaching 30days again but now they say we must wait another 21days for them to close the account.
