Treated like a *****

I have been an ABSA Home Loans customer for almost 20 years. I have 3x bonds and have serviced them without interruption for a combined period of almost 45 years. I phoned ABSA to get my tax certificates, they put me through authentication and I failed. Again I tried and I failed!! Now my account has been locked, the online banking is useless and the app doesn't work. I emailed the help desk and they won't help me because I sent the email from one of my other addresses!! Now I have wasted another week and will wait another 5 days to get feedback!! I just want to get my tax certificates, surely this matter can be resolved in a better and quicker way!! I am not a ********, I have paid millions over to you for my home loan! The attitude is shocking, one of complete lack of help, whether it is the call centre or email. I bank with FNB and they are only too willing to help, ABSA has a poor attitude and treats their own clients like *******....
