Deceased estates what a struggle

My dad passed away on the 11th of December. He still hsve accounts with Absa. The bond and credit card. Now that Im the executor of the estate and would like to find out the balance of the account and to get a settlement its a struggle to talk to the right person. Than they put you through to credit card than its a late estate so I have to talk to deceased estates. Than this number is engaged. Than this than that. Its one big frustration. I wanted to do a late estate account and want to know about fees , they dont know. This is a tired process.
