Standard Bank still cannot just change an email address

I have repeatedly asked Standard Bank to use my gmail account to send me my monthly statements. I visited the branch after traveling almost 15 kilometers, I wrote repeated emails, made many calls and this I was sent my Buriness Account to the wrong email again. Standard Bank is a major institution that over many years earned an incredible amount of many from me. They are unable to attend to the simplest of requests just to use the fight email address. And then we complain about government institutions. It is mind boggling to describe the depts of frustration I experience about this simple manner.
