Standard Bank won't allow email address updates over the Internet

Standard Bank have not only regressed with their new website, they have made things less secure and more inconvenient. I wanted to change my email address. Every other institution allowed me to do so after logging in and/or entering a pin sent to my phone. Only Standard Bank remains. They first insisted that I send, via hackable, insecure email: "- Account number; - ID number; - What is your ATM Cash withdrawal limit; - Name any debit orders going off your account; - What other accounts do you hold with Standard Bank". After reluctantly complying, I was THEN told that I had to visit a branch, because they were not allowed to change my address "for security reasons". When I said that I would switch to FNB if they couldn't do it, they ignored that and said that I could phone instead. This is NOT progress; this is a step back to the dark ages.
