Standard bank ignores requests and has useless contact details

I have repeatedly asked Standard Bank to use my new gmail password that they have on record instead of the old one for sending my monthly statements. I even visited the bank personally to do so. They STILL use my old password, despite all the requests. And to phone them is useless. The phones are not answered or there are long, expensive attempts to get to the right person. I asked repeatedly for them to call ME, but all in vain. I get messages that I should phone them, and then I waste time and money on these calls.
