ABSA don't care about customers!!

I have been trying to get a paid up letter from ABSA now for more than weeks with absolutely no response or assistance. I started with a handful of branch visits where they always had to call someone and I had to explain the story over and over again. Eventually I was told to send my query to *** which I did last Tuesday. I received an automated response acknowledging my request with a promise of a day turnaround. Until today no response. I have been a customer for more than 25 years and my bond has been with ABSA. What must I do to get help?
