Standard Bank Poor Service

All i want to do is get some kind of assistance for my mother, to set up an executer of her estate, this has been the most frustrating process of my life, taking a few months and im nowhere closer than i was last year. Standard bank has the worst service i have ever experienced of all the banks ive dealt with, and your branch managers dont have people skills, i have been to 3 branches in 3 different areas and i have phoned every call center number i can find on the internet, i either cant get through , your phones just ring, or your agents just put me through to different departments, that also dont answer their phones!!
